Mimo wireless system with diversity processing

A Multiple Input/Multiple Output (MIMO) apparatus for implementing Orthogonal Frequency-Division Multiplexing (OFDM) system with diversity processing for decoding sub-channels data of received orthogonal multipath signals arriving at the at least two or multiple antennas, the MIMO baseband processing system comprising:

• at least one each Guard Interval Removal adapted to the receiver and is configured to remove cyclic-prefix for each sub-channels signal;
• an M-point Complex Fast Fourier Transform (FFT) Processor adapted to receive multipath orthogonal baseband components I and Q from the Receiver and is configured to compute complex Fast Fourier Transform coefficients for each of the M sub-channels data;
• at least one each Post-Processor adapted to receive orthogonal signals on the corresponding one of the M sub-channels data from the M-point Complex FFT Processor, wherein an M-ary QAM Demodulator adapted to receive signals from the complex FFT Processor and is configured to demodulate the receive signals into sub-channel baseband component I and Q signals;
• and
• at least M-multiple Turbo Codes Decoders adapted to receive data from the M-point Complex FFT Processor corresponding to each sub-channel to process the data from each sub-channel to produce decoded data output.
