摘要

数字通信的发展趋势为码分多址(CDMA)的商业应用打开了大门。本文建立了非线性和移动信道对同步QPSK码分多址(CDMA)系统性能影响的分析模型。分析中考虑了行波管功率放大器的am - am和am - pm转换、下行热噪声和多径衰落移动信道的综合影响。从误差概率的角度探讨了系统性能。

Performance analysis of synchronous DS-CDMA in mobile nonlinear satellite channel

Trends in digital communications are opening up commercial applications to code division multiple access (CDMA). The paper presents an analytical model for the effects of nonlinearities and mobile channel on the performance of synchronous QPSK code division multiple-access (CDMA) systems. The combined effect of both the travelling wave tube (TWT) power amplifier exhibiting AM-to-AM and AM-to-PM conversion, down-link thermal noise and the multipath fading mobile channel are taken into consideration in the analysis. System performance in terms of the error probability is explored.
