| Abstract: | A blind technique for the simultaneous suppression of narrow band interference (NBI) and both multiple access interference (MAI) and intersymbol interference (ISI) in dispersive channel of code division multiple assess (CDMA) is proposed. This technique is based on the suboptimal subspace blind minimum mean square error (MMSE) algorithm of multiuser detection. In this paper, the performance of blind MMSE detector against NBI, i.e., multitone interferers, autoregressive (AR) interferers, and digital interferers, is analyzed. It is seen that this method outperforms the conventional method of NBI suppression, while simultaneously suppressing the MAI and ISI. |
