摘要
利用13折线PCM编解码,并使用PSK调制,通过高斯噪声信道,接收采用锁相定时提取,恢复PCM解码波形,从而构建了一组完整的语音通信系统的仿真模型。
Based on the theory of PCM encoding, decoding and PSK modulation, with the channel of Gauss noise, the reception is adopted with the method of timing extraction for recovering the PCM decoded waves; and an integrated simulation model of phonetic communication system is designed.
