通信信号瞬时参数的提取方法研究

通信信号的瞬时参数包含丰富的信息,提取瞬时参数具有很重要的意义。本文提出一种时域提取瞬时参数的方法-OSR,并与其它常用方法作了比较。理论分析和实验结果表明,OSR方法在对抗各种信号失真及干扰方面具有优越性,能在恶劣的条件下较准确地逼近真实的瞬时参数。

Research of Instantaneous Parameter Estimation for Communication Signals

The instantaneous parameter estimation for communication signals is very important,for such parameters are abundant of information.In this paper we propose a new approach called orthogonal signal reconstruction(OSR).A further analysis and experiments show that,in the conditions when SNR is very low,or the signal distortion is severe,the OSR approach performs far better than other conventional approaches.
