| 摘 要： | 本文利用离散小波包变换（ＤＷＰＴ）导出信号窨的诱导小波包基。在此基础上建立起基于ＤＷＰＴ的小波包多载波传输系统的概念，提出了最佳小波包多载波市制解调技术。技术根据给定的信道特性，采用类似于最佳基搜索城众多的小波包多载波市制解调方案中快速寻求出最佳方案，使得系统解调出的信号中所要信号与符号间干扰的信干比在不增强噪声的前提下达了最大。

| Abstract: | In this paper,the induced wavelet packet bases of signal space is derived from discrete wavelet packet transformation(DWPT) Upon this basis a concept of DWPT based wavelet packet multicarrier transmission system is established,and the optimal wavelet packet multicarrier modem technique is proposed For the given characteristic of channel,the optimal wavelet packet multicarrier modem scheme can be selected from enormous candidate schemes using a fast searching algorithm similar to the best basis method,which maximum the desired signal to intersymbol interference ratio of the demodulated signal without enhancing the noise |
