| 摘 要： | 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

| Abstract: | When it is transmitted by the FH (Frequency Hopping) system, the analog signal is lost. After evaluating the result of our experiment, the voice quality restricted by channel switching time and hopping rate is discussed. The result can be used in choosing channel switching time and the hopping rate design a frequency hopping system. |
