估计出该时间段内任意符号时刻上的信道响应值.用仿真方法研究了WCDMA上行链路性能与移动台速度的关系、最佳多项式阶数和最佳时隙数

并与WMSA方法进行了比较.

Abstract

A method based on assisted-pilot and polynomial model is proposed for high speed mobile environment.Radio channel response at any time instant is estimated from the received pilots of two or more time slots

assuming that channel response can be modeled as a polynomial.For WCDMA (Wideband Code Division Multiple Access) uplink

the relation between the link performance and the mobile speed are studied by simulation.The optimal polynomial order and the optimal number of time slots are also investigated.Performance comparison between the proposed method and the WMSA (weighted multi-slot average) method is made from the simulation results.
