Abstract :
A novel digital image suppression technique for binary phase shift keying (BPSK) receivers, based on independent component analysis (ICA), is presented. The technique requires only one antenna and a single downconversion path. The highly selective image rejection filter at the RF stage is eliminated. Also, the resulting receiver´s complexity is much lower than that of quadrature or dual-antenna receivers. Simulation results confirm that the performance of the simplified receiver is comparable to the other more complex receivers.
