模拟话音在通过跳频通信系统传输时，在跳频信道切换时间内话音信号丢失，话音质量下降．本文通过实验评估了丢失一部分信号后话音的质量，在此基础上研究了在跳频体制下传送模拟话音时，保证一定话音质量对跳频信道切换时间以及跳频速率的限制．以供模拟跳频制式下选择跳频速率及分配信道切换时间作依据 When the analog voice is transmitted through the frequency hopping communication system, the voice signal is lost during the time hopping channel switching, and the voice quality is degraded. In this paper, the quality of voice after losing some of the signal is evaluated experimentally. On the basis of this, we study the limitation of certain voice quality on hopping channel switching time and frequency hopping rate when transmitting analog voice in frequency hopping system. It is used to select the frequency hopping rate and allocate channel switching time under the mode of analog frequency hopping
