Abstract:

A method and system are provided for processing communication signals. In one embodiment, the method has the steps of providing a data signal based on a communication signal transmitted from a transmitting source, processing the data signal to determine if the data signal has acceptable error characteristics, requesting retransmission of the data signal if the data signal does not have acceptable error characteristics, coherently and jointly equalizing the data signal and the retransmitted signal to produce an equalized signal, decoding the equalized signal to provide an equalized and decoded signal, processing the equalized and decoded signal to determine if the equalized and decoded signal has acceptable error characteristics, and repeating the requesting, equalizing, decoding and processing steps as long as the equalized and decoded signal has unacceptable error characteristics.
