1. A method of decoding quantized and unquantized wanted data symbols from received signal samples, comprising:

  • processing a group of currently received signal samples to determine a corresponding current set of unquantized wanted data symbols and an interfering waveform representative of a sum of other unwanted data symbols by subtracting an amount of a previously decoded set of quantized wanted symbols and a previously determined interfering waveform; and

    quantizing said determined current set of unquantized wanted symbols to obtain corresponding quantized symbols.
