Abstract
In wavelet packet modulation (WPM) system, the application of the linear minimum mean square error (LMMSE) channel estimation algorithm is limited by the nonlinearity of the fading WPM signal. To solve the problem, a simplified linear signal model (SLSM) matching with the LMMSE algorithm is established in the paper. The establishing of the SLSM is based on the fading channel and the orthogonality of WPM signals. The analysis and simulation results show that, the SLSM is matched with the LMMSE algorithm, and the SLSM based LMMSE algorithm can improve the WPM system performance effectively in frequency-selective fading environment.
