AR自编码扩频通信系统的研究

Study of AR Self-Encoded Spread Spectrum System

在自编码扩频通信原理的基础上,介绍了利用自回归(Auto-Regressive,AR)滤波的方法从信源序列中提取扩频码的AR自编码扩频系统,并对该系统的误码性能和多址通信能力进行了理论分析和仿真.结果表明,AR自编码扩频系统改善了普通自编码扩频系统的误码性能,提高了系统的多址能力,为自编码扩频通信的实际应用提供了可选的方案.

Based on the principle of Self-encoded spread spectrum communication, AR-SESS system which employs AR filter technique to obtain the spreading codes from the source sequences is introduced. The performance of Bit-Error-Rate （BER） and the multiple access capability of this system are analyzed and simulated. The analysis and simulation results show that AR-SESS improves the BER performance of the conventional SESS system and enhance the performance of the multiple accesses. It provides a good choice for practical application of the SESS svstem.
