Beamforming and Processing of Broadband Wireless Signals Based on Wavelet Packet Decomposition

AbstractIn the broadband wireless communication, the signal processing may have these problems in the frequency aliasing and frequency offset. This paper presents an improved wavelet decomposition and reconstruction algorithm for the different properties of wireless signals in the interference. In order to achieve much better beamforming with low noise, this paper discusses the issue about beamforming and processing of broadband wireless signals based on wavelet packet decomposition. Simulation results show the effectiveness for the accuracy and calculation speed, and the results also prove that this method can have a strong anti-Doppler shift performance
