or not it is beneficial fig6 is block diagram of a receiver 600 configured to perform knowledge based interference cancellation and blind interference cancellation selectively in accordance with another embodiment of the present invention the receiver 600 includes a knowledge based interference cancellation unit 602 a blind interference cancellation unit 604 a demodulator 606 and a trade off management unit 608 the knowledge based interference cancellation unit 602 cancels interference based on u201c pre known u201d knowledge and the blind interference cancellation unit 604 cancels interference without the pre known knowledge the knowledge based interference cancellation unit 602 and the blind interference cancellation unit 604 are selectively turned on and off under the control of the trade off management unit 608 the trade off management unit 608 considers a plurality of trade off factors and determines which interference cancellation be performed for example ica can separate out signals as one gaussian signal under specific conditions therefore it may be advantageous to defer some signal removal from the knowledge based processing to the blind processing even though the knowledge based processing may handle that signal one reason is that a premature removal of specific signals will decrease the effectiveness of the central.
