Abstract:
1. An apparatus comprising: a transmitter to wirelessly transmit data having a plurality of symbols utilizing a first sub-carrier frequency mapping; and a hardware module to cause the transmitter to retransmit the data utilizing a second sub-carrier frequency mapping such that at least one said symbol in the data is retransmitted wirelessly over a sub-carrier frequency that is different from a sub-carrier frequency previously used to transmit the at least one symbol, wherein the second sub-carrier mapping is selected from a plurality of sub-carrier frequency mappings pre-generated to account for an environment the transmitter is located in, wherein the second sub-carrier is selected based upon an increased likelihood that symbols that were not successfully transmitted will be successfully retransmitted; and a communication module that demodulates a combined packet that includes original and retransmitted symbols in the combined packet, wherein the communication module obtains an optimal weighted average of the symbols of packets of the combined packet.
