摘要
本文提出一种用于大容量数字微波通信系统误码性能恶化的计算方法——恶化量综合法。该方法与传统的恶化量累加法相比,更接近于实际系统的工作情况。用这种方法对64QAM 140 Mb/s中频调制解调系统的总体设计中的指标进行了分配,由此测得的结果与分析模拟结果基本符合。
A computation method of error performance degradation for high capacity digital microwave radio communication systems is proposed. It is more agreeable to reality than the classical method of adding up and called integrated degradation method (IDM). The IDM has been used to project the error performance specification of a 64QAM 140Mb/s IF modula.ion and demodulation system. The measurement results have accorded with the predicted by the IDM well.
