介绍了一种基于DSP平台的话音带宽短波信道模拟器。该模拟器不仅可以模拟短波信道的主要特点,如多径传输、瑞利衰落、多普勒频移等,而且实现了对传输信号的全数字化实时处理。
This paper introduces a speech bandwidth short-haul channel simulator based on DSP platform. The simulator can not only simulate the main features of short-wave channel, such as multipath transmission, Rayleigh fading, Doppler shift, etc., but also realizes full digital real-time processing of transmitted signals.
