Patent ID: 8514958

Claim:
An Orthogonal Frequency Division Multiplex (OFDM) communication system comprising: a plurality of OFDM transmitters; at least one OFDM receiver for receiving an OFDM signal from a first OFDM transmitter of the plurality of OFDM transmitters; and at least one transmitter for transmitting a subcarrier status data to the OFDM receiver, wherein the subcarrier status data is indicative of active subcarriers for a number of OFDM transmitters not communicating with the OFDM receiver; wherein the OFDM receiver comprises: a receiver for receiving a signal comprising a desired signal component from the first OFDM transmitter and interference from at least one interfering OFDM transmitter of the plurality of OFDM transmitters, and for receiving the subcarrier status data, channel estimator for determining channel estimates for at least an air interface communication channel from the first OFDM transmitter and an air interface communication channel from the at least one interfering OFDM transmitter, a processor performing mitigation of the interference using the subcarrier status data for the number of OFDM transmitters other than the first OFDM transmitter and the channel estimates for the at least one interfering OFDM transmitter.
