话带Chirp信道估值的性能

On the Property of Chirp-Based Voiceband Channel Evaluation

本文首次分析了话带Ｃｈｉｒｐ信道估值的性能，分析了话带Ｃｈｉｒｐ的多径效应和多普勒效应，分析了多径和多普勒效应相互影响的基本原理，以及减小这种影响的主要途径，并由计算机模拟作了性能比较。

Based on the voiceband chirp signal,the property of channel evaluation and the principles of multipath and Doppler and their effects on each other are analyzed. The main way to eliminate the effects is presented. Finally,the computer simulation shows the correct results.
