Abstract:
1. A method for correcting errors received over a communication link, comprising: receiving a first retransmission of a packet at a back end of a receiver, wherein the first retransmission of the packet originates from a channel encoder; determining that the packet is corrupted if the packet has an error which is uncorrectable using one or more of the first retransmission or an initial transmission of the packet; performing a first level of error correction at a front end of the receiver based upon a second retransmission of the packet, wherein the second retransmission of the packet originates from a Peak-to-Average Power Ratio (PAPR) management module encoder; determining if the corrupted packet was corrected by the first level of error correction; and performing a second level of error correction at the back end of the receiver based upon a third retransmission of the packet if the corrupted packet was not corrected by the first level of error correction, wherein the third retransmission of the packet originates from the channel encoder.
