An MMSE-based compressive domain interference cancellator for wideband systems

Compressive sensing enables us to reduce the sampling rate below the Shannon Nyquist sampling rate. Unfortunately, in wideband systems, compressive sensing based signal processing often includes the undesired signals. In a previous work, ZF based method was proposed for interference cancellation. However, ZF based method do not consider the effect of noise. Moreover this method causes the degradation of desired signal. In this paper, we propose an interference cancellation method in compressive domain based on MMSE algorithm. The simulation results manifest that the proposed method improves the performance of reconstruction error rate.
