摘要

在这项工作中，寻找更好的小波包树结构，以减少在实际的两路低压电力线信道或两路多径信道上基于Daubechies小波的OFDM系统的ISI和ICI功率(集成功率)之和。采用暴力破解算法得到了较好的小波树结构。结果表明，在相同的带宽占用下，改进的小波包树结构比传统的Mallat结构性能更好。

Searching better wavelet packet tree for ISI and ICI reduction in WOFDM

In this work, better wavelet packet tree structures are searched to reduce the sum of ISI and ICI powers (integrated power) in Daubechies wavelet-based OFDM system over a practical two path low-voltage powerline channel or two way multipath channel. Better wavelet tree structures are obtained by using a brute-force algorithm. Results show that better wavelet packet tree structures perform better than conventional Mallat structures for the same bandwidth occupancy.
