Adaptive blind equalization for ultra wideband system
一种基于自适应算法的超宽带系统盲均衡技术

A new adaptive blind equalization technology was proposed for Direct Sequence-Ultra WideBand (DS-UWB) and Time-Hopping-Ultra WideBand (TH-UWB) wireless communication systems. This method can effectively track the variation of Ultra WideBand (UWB) channels by using the variable forgetting factor to the adaptive algorithm and thus can compensate the interference due to the properties of channels. When receiving the signals, it can adjust the coefficients of equalizers without using the training sequence and then obtain the estimation of the sent signals. Furthermore, this method has relatively rapid convergence rate and good stability. Simulation results show that the proposed method has better performance in tracking UWB fading channels and it also help obtain lower Bit Error Rate (BER).
