Abstract :
We propose a low complexity active interference cancellation method applicable for OFDM based cognitive radios. The motivation for the new method comes from existing techniques proposed in the literature. We compare the performance of the new method with existing technique by using simulation results to highlight the interference suppression performance, power efficiency, and complexity.
