Abstract:
1. A method for transmitting data using space frequency block coding (SFBC), the method comprising: performing a channel coding on an input data stream to generate a coded data stream; multiplexing the coded data stream to a plurality of multiplexed data streams; obtaining channel state information (CSI); performing power loading based on the CSI on each of the multiplexed data streams; pairing orthogonal frequency division multiplexing (OFDM) subcarriers for SFBC encoding; performing SFBC encoding on the multiplexed data streams; performing eigen-beamforming on the SFBC encoded data streams based on the CSI to distribute eigenbeams to a plurality of transmit antennas; and performing inverse fast Fourier transform (IFFT) for converting the eigen-beamformed data streams to time domain for transmission.
