提出了一种采用前向纠错编码的复合位置码并行组合扩频通信系统（CPC/PC/SS），并对其性能进行了分析。采用FEC编码方案的CPC/PC/SS系统可以设计出更高的数据传输能力，甚至是高斯信道下普通PC/SS系统的数倍。所提出的FEC编码分别应用于正交码的组合数据及其传输正交码的状态数据，并且该编码方案对正交码的状态数据采用较少的冗余FEC码就足够了。因此，总信息速率超过了应用常规的总FEC编码所提供的信息速率。仿真结果表明，采用该FEC编码的CPC/PC/SS系统的误码率性能低于传统的PC/SS系统。
Complex Position Code Parallel Combinatory Spread Spectrum (CPC/PC/SS) communication system with forward error correction (FEC) coding scheme is proposed in this paper, and performances are analyzed. CPC/PC/SS system with FEC coding scheme can be designed to have higher data transmission capability, even several times compared to ordinary PC/SS system on Gaussian channel.The proposed FEC coding is separately applied to the combination data of orthogonal codes and the state data of their transmitting orthogonal code, and less redundant FEC code is enough to the state data of orthogonal codes by this coding scheme. Therefore, the total information rate exceeds that offered by the conventional overall FEC coding is applied. Simulation results show that the error rate performance of the CPC/PC/SS systems equipped with the proposed FEC coding is lower than conventional PC/SS system.
