Claim 9:
10. A system for introducing time diversity in a transmitter, the system comprising:
control circuitry coupled to a transmitter configured to:
receive a request to retransmit data, wherein the request indicates a retransmission number;
obtain a plurality of bits;
parse the plurality of bits into a plurality of streams;
encode the plurality of streams into a plurality of symbols;
map the plurality of symbols to a respective plurality of tones based on the retransmission number, wherein the mapping is time-varying, by:
arranging the plurality of symbols into an interleaver matrix, and
modifying, based on the retransmission number, a plurality of rows of the interleaver matrix; and

generate, based on the time-varying mapping, a plurality of time-domain signals; and
the transmitter configured to:
transmit the plurality of time-domain signals.
