Abstract:
1. A method of transmitting in a multiple-input-multiple-output (MIMO) transmitters receivers system, comprising: adaptively selecting a coding mode of each orthogonal frequency division multiplexing (OFDM) sub-carrier symbol of a data stream to be set either in a diversity mode or in a multiplexing mode according to a feedback data packet having a coding information of the OFDM subcarrier symbol; grouping subcarriers symbols coded according to the multiplexing mode in a first group; grouping subcarrier symbols coded according to the diversity mode in a second group; transmitting the subcarrier symbols of the first group by a first antenna and the subcarrier symbols of the second group by a second antenna; adaptively grouping receivers according to said coding grouping information received with said feedback data packet to at least a first receivers group and a second receivers group; decoding subcarrier symbols coded according to a multiplexing mode by the first receivers with a multiplexing code decoding scheme; and decoding subcarrier symbols coded according to a diversity mode by the second receivers with a diversity code decoding scheme.
