Interference Suppression for Mobile Communication Signals in Urban Architecture
Bo Chen · Jisuanji gongcheng · 2013
The problem of Narrow Band Interference(NBI) and both Multiple Access Interference(MAI) and Intersymbol Interference(ISI) in dispersive channel of the cellular mobile communication under urban architecture's influence is proposed,a technique for the simultaneous suppression of NBI,i.e.,multitone interferers,autoregressive interferers and digital interferers,and both MAI and ISI,and environmental noise is considered.This technique is based on the suboptimal subspace blind Minimum Mean Square Error(MMSE) detector of multiuser detection with the auxiliary vector to make it low-complexity.It is seen that when SNR is 10 dB,BER of blind MMSE detector is lower than about 3 dB of the conventional ways'.
