摘要

分析了存在共信道干扰时相干最小移位键控匹配滤波器解调的平衰落信道性能。结果表明，在中心频率处，连续波是最有害的干扰。误码率(BER)性能首先表征了非衰落信号和地面视距场景的典型干扰。随后的分析讨论了衰落信号与非衰落干扰(典型的长天波或闪烁通信路径和本地干扰)，衰落信号与衰落干扰(典型的卫星通信性能在电离层衰落和远程干扰)，以及非衰落信号与衰落干扰。在衰落信号条件下，无论干扰是恒定的(短距离)还是衰落的(远距离)，性能都是极差的;要使这种信道可用，就需要使用分集技术。

MSK performance under various fading conditions in the presence of worst-case CW interference

The author analyzes the flat-fading-channel performance of coherent MSK (minimum shift keying) matched filter demodulation in the presence of cochannel interference. It is shown that the most deleterious interference is CW (continuous wave) at center frequency. Bit error rate (BER) performance is first characterized for nonfading signal and interference typical of a terrestrial line-of-sight scenario. Subsequent analyses address fading signal vs. nonfading interference (typical of a long skywave or scintillation communication path and local interference), fading signal vs. fading interference (typical of satellite communication performance in ionospheric fading and remote interference), and nonfading signal vs. fading interference. The performance under fading-signal conditions, regardless of whether the interference is constant (short range) or fading (long range), is extremely poor; to be usable, such channels will require the use of diversity techniques.<>
