| 摘 要： | 本文介绍了带内振幅色散合路器的工作原理,提供了一种估算衰落信号参数的方法.计算机模拟结果表明:采用该方法可以计算出使带内振幅色散最小时所对应的移相值,简化了合路器的控制.在实验室利用中频静态衰落模拟进行的模拟试验表明:最小振幅色散合路器可以显著减少合路信号的带内振幅色散,改善通信系统的性能.

| Abstract: | This paper briefly describes the theoretical analysis for the operation of IF combiner.A method of estimating fading signal parameters which can simplify the control of IF combiner is proposed. The results obtained from the simulation experiments in laboratory show that the combiner significantly reduce the in band amplitude dispersion caused by multipath fading in a high capacity digital microwave radio,and can improve the performances of communication systems. |
