Iterative known interference cancellation in OFDM systems
Collision resolution via interference cancellation (IC) in packet-based random multiple access (RMA) systems is a promising technique to decrease number of retransmissions and increase overall throughput. This paper proposes novel iterative algorithm of IC in OFDM systems for the case when one of the interfering packets is known to the receiver. Comparing to well-known successive interference cancellation (SIC) methods, proposed algorithm works when there is no significant power imbalance in received signals and receiver could not decode the strongest one. The algorithm exploits the property, that duration of channel response in time domain is constrained while residual interference is widespread over the frequency and time.
