In this article, we introduce the basic principle of the self-encoded direct spread (SEDS) system, construct the model of the system, and analyze the main performances of the system, such as BER performance, self-interference, MAI performance and so on.

• 本文介绍了自编码扩频系统的基本原理,构建了系统模型,并对其主要性能,如误码率性能、自干扰特性、多址能力和抗多径干扰能力等作了分析。
