摘要： In a communications system wherein a broadcast signal is received by a plurality of antennas each connected to a receiver, the resulting plurality of received signals are jointly subjected to automatic frequency correction (AFC) before interference rejection combining (IRC) or maximal ratio combining (MRC) processing to output an estimate of the broadcast signal. The joint automatic frequency correction processing involves computing and applying a frequency offset on a sample by sample basis to each of the received signals to output corresponding frequency corrected received signals for IRC or MRC processing.
