Abstract:
A method for joint detection of a coded input signal in CDMA system comprising:demultiplexing a first decoder input signal to produce a first plurality of decoder input signal portions, each of which corresponds to a decoder of a plurality of decoders; decoding, by each decoder of the plurality of decoders, the corresponding decoder input signal portion of the first plurality of decoder input signal portions to produce a current set of recovered symbols; subtracting a previous set of recovered symbols from the current set of recovered symbols to produce a symbol difference; generating a correction signal from the symbol difference; subtracting the correction signal from the first decoder input signal to produce a second decoder input signal; demultiplexing the second decoder input signal to produce a second plurality of decoder input signal portions, each of which corresponds to a decoder of the plurality of decoders; decoding, by each decoder of the plurality of decoders, the corresponding decoder input signal portion of the second plurality of decoder input signal portions to produce a subsequent set of recovered symbols.
