- 摘要：In the field of data mining,it is often encountered to perform cluster analysis on large data sets with mixed numeric and categorical values.However,most existing clustering algorithms are only efficient for the numeric data rather than the mixed data set.For this purpose,this paper presents a novel clustering algorithm for these mixed data sets by modifying the common cost function,trace of the within cluster dispersion matrix.The clonal selection algorithm (CSA) is used to optimize the new cost function,since the clonal operator can combine the evolutionary search and random search,and incorporate the global search with local search,by the clonal operation on candidate solutions;the new algorithm can quickly obtain the global optimum.Experimental result illustrates that the CSA-based new clustering algorithm is feasible for the large data sets with mixed numeric and categorical values.关键词：cluster analysis;numeric data;categorical data;clonal selection algorithm3|1725|5更新时间：2025-07-16

- 摘要：Three beamforming methods using estimated steering vectors of coming signals in smart antenna are proposed.Based upon the signal model and the multipath channel model of CDMA,the steering vectors of mainpaths of users are estimated by using code filtering method.Then restrictive conditions of recovering desired signal and constraining interferences are formed by using these estimated steering vectors.Least square(LS) beamforming method is proposed directly from these restrictive conditions.Generalized minimum variance distortionless response(GMVDR) method is proposed by minimizing the output power based upon the restrictive conditions.Extended minimum variance distortionless response(EMVDR) method is also proposed by introducing dummy signals for constraining side lobes based upon GMVDR method.Simulation results show desired signal is recovered and interferences and noise are constrained perfectly in these methods.By comparison,it is proved that the beamform in EMVDR method is the best.关键词：time of arrival (TOA);direction of arrival (DOA);code filtering method;least square (LS) method;generalized minimum variance distortionless response (GMVDR) method;extended minimum variance distortionless response (EMVDR) method2|1326|3更新时间：2025-07-16

- 摘要：Aperture jitter heavily affects the performance of an intermediate frequency or radio frequency bandpass sampling system.In theory,although the IF signal and baseband signal with the same bandwidth can be sampled using the same frequency,sampling an IF signal is effected by jitter more badly,and its sampling techniques are more difficult.If the aperture jitter issues of IF sampling system can not be well solved,it will be very possible to miss the right digital signal.The paper analyzes the causation of inducing aperture jitter,and the relationships between aperture jitter,SNR of ADC and the highest frequency of sampled signal.It presents the reasons of introducing the error between the highest frequency of sampled signal and analog bandwidth of ADC,and finds out the relationship of over-sampling ratio and gain processing and aperture jitter among IF sampling system.At last,it introduces several actual methods to reduce the aperture jitter.关键词：aperture jitter;bandpass sampling;baseband sampling;signal-to-noise ratio;high speed ADC;digital intermediate frequency sampling2|2197|9更新时间：2025-07-16

- 摘要：Recent work has shown that capacity of a multiple-antenna MIMO system is increased linearly with the number of transmitter antennas in fading channels.For a poor scattering environment,the low-rank channel may result in a substantial degradation of capacity although fading is independent.In this situation,antenna selection is an effective way to reduce cost.Capacity of a low-rank MIMO channel with antenna selection is studied.The results of simulation show that antenna selection of transmitter not only can increase capacity,but can also reduce complexity and cost of RF chains for given channels.Antenna selection of receiver also can reduce cost under the condition of not decreasing capacity.关键词：antenna selection;multiple-antenna MIMO system;channel capacity;rank2|1095|4更新时间：2025-07-16

- 摘要：To address the problem of TCP end-to-end congestion control,IETF advocates deploying active queue management (AQM) mechanisms in the TCP/IP networks.Several popular AQM algorithms,such as RED (Random Early Detection),BLUE,ARED (Adaptive RED) and SRED (Stabilized RED),are compared based on simulations and the performance metrics used in the study are queue size,packet drop probability,packet loss rate,throughput on different connections and link utilization on different buffer size.The simulation results indicate that in all these aspects,the performance of BLUE,ARED and SRED are better than that of RED.Furthermore,ARED and SRED can stabilize queue size and control packet loss rate effectively thus they maintain high link utilization,bounded delays and more certain buffer provision.关键词：Internet;AQM;RED;BLUE;ARED;SRED2|1927|6更新时间：2025-07-16
- 摘要：A user fair active queue management algorithm named UFQ is introduced.UFQ aims at fairly distributing the network resources among users in various situations.Fairness here means different users who have different profiles will get network resources proportionally.User's utility is defined.User's Packets will be inserted a label with its utility in network edge.During network congestion,UFQ will drop or mark packets according to utility inserted in packets.So it distributes network resources among users with average utility.UFQ requires neither admission control nor signaling.Edge router maintains per flow state and core router maintains no flow state.Only one FIFO queue is kept in each node.With simulation and experiments of TCP and UDP traffic,UFQ has shown good performance on quality of service.关键词：utility;fairness;queue management2|874|1更新时间：2025-07-16
- 摘要：Fine granular scalability (FGS) coding method has fine-grained scalable capability and can be adapted to dynamic variation of network bandwidth.So it is considered as a good coding scheme suitable for video transmission over network.But current MPEG-4 FGS coding standard is not efficient,which will restrict its application.Therefore,a quality fine granular scalable coding scheme for head shoulder sequence images,which are commonly seen in video applications,is implemented in this paper.The base layer is encoded with H.26L and the residual signal between the original image and the reconstructed image from base layer is encoded with a DCT-based SPIHT coding method to achieve the enhancement layer bit stream.Automatic human face detection and tracing algorithm in a complex background is combined with selective enhancement technique to encode human face region with high priority.Experimental results show that the overall coding efficiency gain of this method is higher than that of MPEG-4 FGS standard and the bit stream is fine granular scalable.The subjective perceptual quality of reconstructed human face region can be selectively improved.关键词：head shoulder sequence images;fine granular scalability;H.26L;selective enhancement;SPIHT algorithm2|933|0更新时间：2025-07-16

- 摘要：A new transmission scheme called Dynamic Batched Patching was proposed to solve the problems,such as the low utilization of system resources and poor quality of service,existing in the existent schemes for video stream on demand. The key intuition behind this proposed schedule is that requests are dynamically batched according to the request arrivals,each batch of requests is served over one or two channels-either a regular channel alone or the combination of a regular channel and a patching channel.We derive a closed-form expression for the transmission channel requirements for this scheme.Our simulation experiments and theoretical arithmetic demonstrate that the proposed scheme can significantly outperform the existing schemes and it can be applied in random-scale On-Demand system.关键词：VOD;video stream;transmission scheme;dynamic batched patching2|815|2更新时间：2025-07-16
