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.
This paper introduces the working principle of the in-band amplitude dispersion combiner and provides a method to estimate the parameters of the fading signal.Computer simulation results show that this method can calculate the phase shift value corresponding to the minimum in-band amplitude dispersion, Which simplifies the control of the combiner.Mining experiments in the laboratory using the intermediate frequency static fading simulation show that the minimum amplitude dispersion combiner can significantly reduce the in-band amplitude dispersion of the combined signal and improve the performance of the communication system.
