Abstract

Wavelet packets have found many applications in communications. Promising results have been obtained for a number of modulation schemes based on wavelet packets. However, effects of multipath and time-varying wireless communication channels on these wavelet packet signature waveforms have not been seriously dealt with. We present a method to model complex time-varying wireless communication channels using wavelet packets as bases. This model has the advantages of flexibility, efficiency, and accuracy. Test results using field measurement data show the effectiveness of our model.

基于小波包的时变无线通信信道模型
小波包在通信中有许多应用。许多基于小波包的调制方案都取得了令人满意的结果。然而，多径和时变无线通信信道对这些小波包特征波形的影响并没有得到认真的研究。提出了一种以小波包为基础的复杂时变无线通信信道建模方法。该模型具有灵活、高效、准确等优点。现场实测数据的测试结果表明了该模型的有效性。
