摘要
Systems and methods are provided for transmitting information between an intended source and a receiver to minimize co-channel interference from at least one interfering source. Pilot subcarriers and data subcarriers may be broadcast from an intended source and at least one interfering source. The pilot subcarriers may be shared across base stations or distributed among base stations in frequency, in time, or both. In addition, the frequency reuse factor of the pilot subcarriers may be different than the frequency reuse factor of the data subcarriers A receiver receives a composite signal that corresponds with an intended signal from an intended source and an interfering signal from at least one interfering source. The portion of the received signal that corresponds to the intended signal may be recovered by the receiver based on the broadcast of the pilot subcarriers.
