The system comprises a subcarrier status data controller for transmitting subcarrier status data to the OFDM receiver. The subcarrier status data indicates the active subcarriers of the OFDM transmitters. The OFDM receiver comprises a receiver which receives a signal comprising a desired signal component from a first OFDM transmitter and interference from at least one interfering OFDM transmitter. The OFDM receiver further comprises a subcarrier status processor which receives the subcarrier status data and a channel estimator which determines channel estimates for at least an air interface communication channel from the first OFDM transmitter and an air interface communication channel from the interfering OFDM transmitter. An interference mitigation processor performs interference mitigation of the interference in response to the subcarrier status data and the channel estimates."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interference mitigation for orthogonal frequency division multiplexing communication","description":"An Orthogonal Frequency Division Multiplex (OFDM) communication system comprises OFDM transmitters and an OFDM receiver.
