摘要

研究了衰落环境下跳频扩频多址通信的性能。数据在载波上传输，使用差分相移键控，每跳多个数据位(即，慢跳频)。跳频和脱频是非相干的。考虑了具有各种数据脉冲波形和信道延迟功率密度谱的系统的频率选择性衰落信道。给出了平均误差概率的解析结果，并给出了最有趣的数值例子。

Effects of Frequency-Selective Fading on Slow-Frequency-Hopped DPSK Spread-Spectrum Multiple-Access Communications

This paper is concerned with the performance of frequency-hopped spread-spectrum multiple-access communications in a fading environment. The data is transmitted on the carrier using differential phase-shift keying with multiple data bits per hop (i.e., slow frequency hopping). The frequency hopping and dehopping are noncoherent. Frequency-selective fading channels are considered for systems with various data pulse waveforms and channel delay power-density spectra. Analytical results for the average probability of error are presented, and numerical examples of the most interesting cases are given.
