Abstract

Based on the good time-frequency localization of the wavelet packet modulation (WPM) system and the analysis of the multitone (MT) interference, an improved WPM narrow band interference (NBI) rejection system using an adaptive least mean square (LMS) algorithm is discussed in this paper. In the WPM interference rejection system, according to the structure of the wavelet packet tree (WPT) and the characteristic of the MT interference, the demodulated WPM signal which contains the interference component is filtered using an adaptive LMS filtering implementation. Theoretical analysis and simulation results show that the proposed method improves the bit error rate (BER) performance of the WPM system in the presence of MT interference.
