Xianghong Tang, Shen Chuan-peng, Dong Ting-liang · 2010
It is well known that wavelet packet modulation (WPM) has the flexibility of sub-modulated channel distribution and demodulation method. To improve performance of the WPM for optimization demodulation, in this paper, based on WPM signal, the channel identification is studied by the channel characteristic which is exhibited in the statistical analysis of sub-modulated channel data. Simulation results show that the proposed channel identification method is exactly steady and effective.
