Abstract:
1. A wireless communication receiving apparatus, comprising: an antenna for receiving via first and second wireless communication channels a composite communication symbol that represents first and second communication symbols which each correspond to a result of a coding operation performed by a transmitter apparatus on a bit stream; a probability generator coupled to said antenna and responsive to said composite communication symbol for generating, for said first and second communication symbols, corresponding first and second pluralities of probabilities that the communication symbol has respective ones of a plurality of possible values of the communication symbol; a first SISO decoder for receiving said first plurality of probabilities and producing therefrom a further first plurality of probabilities, an output of said first decoder coupled to an input of said probability generator; a second SISO decoder for receiving said second plurality of probabilities and producing therefrom a further second plurality of probabilities, an output of said second decoder coupled to an input of said probability generator; a de-interleaver coupling an output of said first SISO decoder to an input of said second SISO decoder; and an interleaver coupling an output of said second SISO decoder to an input of said first SISO decoder.
