介绍了短波通信中估计语音质量的主要方法,针对文献[1]中SINAD估计算法的缺点,采用了文献[2]提出的新的短波信道语音质量估计算法──AI估计法,并对其在典型的短波模拟信道上进行了测试,将测试结果与SINAD估计法作了一致性对比分析。结果表明由于调解器的体制限制,AI法仍不能很好地估计语音质量,需用新的探测方案进行改进。此分析可供参照军标定制时参考。
The main method of estimating speech quality in shortwave communication is introduced. Aiming at the shortcomings of SINAD algorithm in reference [1], the new shortwave channel speech quality estimation algorithm ──AI estimation method proposed in reference [2] is introduced, A typical shortwave analog channel was tested, and the test results were compared with the SINAD estimation method. The results show that due to the limitations of the modem, the AI method still can not estimate the speech quality well and needs to be improved with a new detection scheme. This analysis is for reference military standard custom reference.
