本文提出了一种可以有效地实现用户高数据率传输的卷积编码正交扩频多码CDMA系统,以适应未来移动通信业务发展的需求.此系统相似于多载波CDMA系统,对于用户传输的高速率数据首先进行串-并转换,对变换后的低数据流再进行卷积编码,然后再进行正交序列扩频调制.不同于多载波CDMA系统,各支路扩频信号用同一载波进行调制发送.这里,对此系统在Nakagami衰落信道的性能进行了计算,并对数值结果进行了分析.
In this paper
a convolutional enceded orthogonal sequence multicode CDMA system is proposed so as to transmit user’s high rate data to fit the requirement of the services of the future mobile communication. Similar to multicarrier modulation
the higher rate date transmitted by serial-to-parallel is converted at first
and then the lower rate data streams are convolutionally encoded and spreaded spectrum modulated by a set of orthogonal sequence Being different from multicarrier modulationg
all lower branch data streams use single carrier. The performance of the system over Nakagami fading channel is calculated
and numerical result is analyzed.
