| 摘 要： | 小波包调制是一种新型的多载波调制方式。该文主要介绍了小波包调制技术的基本结构，并在频率选择性衰落信道下，采用不同的小波基以及不同子载波数分析了其误码特性，比较了小波调制与小波包调制的性能。仿真结果表明小波包调制在频谱利用率，对抗多径干扰、频率选择性衰落以及码间干扰等方面，较其他多载波调制方式都有一定的优势。

| Abstract: | Wavelet Packet Modulation(WPM) is a new kind of multicarrier modulation.In this paper,the basic structure of the WPM is presented.In the frequency selective fading(FSF) channel,the bit error rate(BER) performance of the WPM is analyzed,using different wavelet basis and different number of the sub-carriers.The performances of the wavelet modulation and the WPM are compared.The simulation results indicate that the WPM is better than other multicarrier modulations in the bandwidth efficiency,combating the multi-path disturbance and the FSF,also the inter-symbol interference(ISI). |
