扩频通信中编码调制与相关接收技术的研究

介绍了扩频通信中数据编码和译码新技术的实现方法及电路组成，重点介绍了ＤＰＳＫ（微分相移键控）、ＭＳＫ（最小移位键控）、ＬＳＩ（大规模集成）相关器及ＣＣＤ（电荷耦合器件）可编程匹配器。通常在组成一个扩频通信系统网络时，遇到的最大难题是如何使硬件技术与信号处理算法相匹配，如何节省频率而且能达到最大的系统容量，另外，还存在高可靠性和低功耗等技术关键问题。

Coding Modulation and Coherent Detection Techniques in Spread-Spectrum Communication

A few data coding-decoding methods developped recently are reviewed with emphasis on DPSK,MSK,LSI correlator and CCD programable matched filter in spread-spectrum circuits.Some approaches which are typically the key techniques in constructing a spread-spectrum communication network, such as to implement DSP with minimized hardware efficiently, to get more system capacity with a reasonable bandwidth, and to make trade-off between higher reliability and lower power consumption, are recommended.
