Abstract:
1. In a wireless transmitter, wherein an input bit sequence is encoded and transmitted over a wireless medium using a plurality of spatial streams each using a plurality of subcarriers, a method of interleaving comprising: parsing the input bit sequence to the plurality of spatial streams; interleaving bits parsed to a first spatial stream using a first interleaving sequence to generate a first plurality of interleaved bits, wherein the first plurality of interleaved bits consist of even bits; and interleaving bits parsed to a second spatial stream using a second interleaving sequence distinct from the first interleaving sequence to generate a second plurality of interleaved bits, wherein the second plurality of interleaved bits consist of odd bits, and wherein each of the plurality of spatial streams corresponds to a signal transmitted over a distinct transmit antenna.
