In this paper, the avoidance problem in detect and avoid (DAA) technology of an orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) is addressed. The focus is on reducing the computational complexity of the active interference cancellation (AIC) technique. Three methods are...
