摘要

研究了一种在AWGN信道上具有错误控制编码的SFH/DS-CDMA二元异步混合系统。我们假设发射机功率不等，信号序列随机时变。研究了两种系统，一种是经典的“单用户”接收机，另一种是多用户“投影接收机”。对于两者，我们分析研究信道编码和签名序列传播之间的权衡，以优化可用处理增益的使用。

Efficient use of the processing gain for coded hybrid SFH/DS-CDMA: analytical analysis

We consider a binary asynchronous hybrid SFH/DS-CDMA system with error-control coding on AWGN channels. We assume the case of transmitters of unequal powers and random time-varying signature sequences. Two systems are studied, one with the classical "single user" receiver, and one with a multiuser "projection receiver". For both, we analytically investigate the trade-off between channel coding and signature sequence spreading to optimise the use of the available processing gain.
