Abstract

This article has provided an intelligent interference cancellation (IC) technique in spatial domain that can be employed in the future cognitive wireless network. The cognitive null control engine is proposed to control the number of nulls of software defined radio (SDR) digital beamformer (DBF) in order to maintain the receiver bit error rate (BER) below 10^-5 over the changing interference and angular spread environments. Due to complexity consideration, the cognitive null control engine is considered to be implemented in the base station receiver of next generation wireless networks.
