摘要 频率选择性快衰落信道的精确估计对接收机性能的提高起着重要作用。本文采用小波基表示频率选择性快衰落信道,并由此提出两种估计时变信道的算法。瑞利快衰落信道下的仿真结果表明,信道估计精度较之传统的LMS和RLS 算法有明显提高。 The receiver performance can be greatly improved by precisely estimating frequency-selective fast-fading channel information. In this paper, frequency-selective fast-fading channel is represented by wavelet-basis and the channel is changed into constant parameter channel. Accordingly, two algorithms are proposed for this purpose, Simulation results show that using proposed algorithm, higher channel estimation precision can be obtained than traditional LMS and RLS algorithms.
