话带Chirp信道估值技术

Chirp-Based Voiceband Channel Evaluation

本文研究了一种新的Ｃｈｉｒｐ信道估值方法，即话带Ｃｈｉｒｐ包络法和Ｃｈｉｒｐ复包络法，研究了话带Ｃｈｉｒｐ的探测机理和实现模型及计算机模拟．其特点是采用高性能的Ｃｈｒｉｐ探测体制，利用现有的话音信道将Ｃｈｉｒｐ信号由频率管理推向信道估值．

The new methods for voiceband channel evaluation called chirp envelope and chirpcomplex envelope are presented.The sounding and realtime realization model and computer simulation are given.Based on the high quality chirp sounding system via voiceband channel,the chirp sounding is realized from frequency management to voiceband evaluation.
