Abstract:
1. A multiple-input multiple output (MIMO) receiver comprising: circuitry to receive a spatially-multiplexed OFDM signal through two or more antennas, the spatially-multiplexed OFDM signal having been transmitted through at least two spatial channels; demodulation and de-mapping circuitry to demodulate and de-map the received spatially-multiplexed OFDM signal to generate estimates of a transmitted signal for each of the spatial channels, wherein the demodulation and de-mapping circuitry is to further slice the estimates to obtain hard decisions for data bit values for each of the estimates; deinterleaver circuitry to perform deinterleaving operations on the hard decisions for the data bit values; and decoder circuitry to process the hard decisions for the data bit values after the deinterleaving operations and generate a decoded bit sequence, wherein the estimates of the transmitted signal comprise de-mapped modulation symbols.
