Abstract

In this contribution, a general approach to suppress image signal and co-channel interference in a wireless receiver is presented. The technique employs diversity reception, and the algorithm is based on complex-valued independent component analysis (ICA). The proposed ICA method increases the channel capacity through greater frequency reuse, and it simplifies the receiver's front end by eliminating the need for analog image filtering. Also, the new technique is computationally efficient and has attractive implementation features in terms of the requirement for A/D converters' speed and bandpass filters' selectivity. Simulation results show that the performance is robust over a wide range of input signal-to-interference ratios, and the algorithm has fast convergence. © Birkhäuser Boston (2004).
