Abstract
Systems and methods for canceling interference in a communication system are described. A signal that comprises current data from a current access point and secondary data from one or more secondary access points is received. The secondary data is demodulated using one or more secondary channel estimates if a signal metric is less than a predetermined threshold. Interference in the received signal is canceled using the demodulated secondary data if the signal metric is less than the predetermined threshold. The received signal with the interference canceled is demodulated using a current channel estimate to obtain the current data. The method for interference cancellation may use the same hardware resources and processing available for receiving data from a single access point.
