Patent ID: 7333421

Claim:
A wireless communication system comprising: an OFDM-MIMO transmitter comprising a multiplexer for dividing a serial bit information stream into a plurality of serial bit information substreams, and a plurality of transmitter chains coupled to said multiplexer, each transmitter chain for receiving a respective serial bit information substream and comprising a serial-to-parallel converter coupled to said multiplexer for converting the respective serial bit information substream to a parallel bit information substream, a signal mapper coupled to said serial-to-parallel converter for receiving as input a first group of bits from the parallel bit information substream, each signal mapper corresponding to a specific subcarrier, an antenna selector having a first input coupled to said serial-to-parallel converter for receiving a second group of bits from the parallel bit information substream, and a second input coupled to said signal mapper for receiving a channel symbol therefrom, a plurality of OFDM modulators coupled to a plurality of outputs from said antenna selector, a transmit antenna coupled to each OFDM modulator, and said antenna selector selecting one of said transmit antennas for transmitting the channel symbol for the corresponding subcarrier based upon the second group of bits from said serial-to-parallel converter.
