Patent ID: 8634499

Claim:
An orthogonal frequency division multiplexing (OFDM) multiple-input multiple-output (MIMO) receiver for performing blind signal separation, comprising: a plurality of receive antennas for receiving signals and generating a plurality of receive data streams; a plurality of radio frequency units for converting the receive data streams to generate a plurality of baseband streams; a plurality of discrete Fourier transform (DFT) units for performing DFT on the baseband streams to generate a plurality of frequency domain data streams; a blind signal separation unit for performing blind signal separation on the frequency domain data streams to recover spatial data streams transmitted by a transmitter; a plurality of subcarrier de-mapping units for performing subcarrier de-mapping on the recovered spatial data streams to generate a plurality of subcarrier de-mapped data streams; a plurality of de-interleavers for de-interleaving the subcarrier de-mapped data streams to generate a plurality of de-interleaved data streams; and a parallel to serial converter for merging the de-interleaved data streams into one frequency domain data stream.
