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 combiner coupled to said probability generator for combining said first and second pluralities of probabilities to produce a plurality of combined probabilities; a SISO decoder corresponding to said coding operation and coupled to said combiner for receiving the plurality of combined probabilities and producing therefrom a further plurality of combined probabilities; a splitter coupled between said SISO decoder and said probability generator for receiving said further plurality of combined probabilities and producing therefrom third and fourth pluralities of probabilities that respectively correspond to said first and second communication symbols; and said probability generator operable for generating said first and second pluralities of probabilities also in response to said fourth and third pluralities of probabilities, respectively.
