Abstract:
1. A method for efficient decoding of block product code format signals, the method comprising: providing signal values r providing average values a1=(v1+v2+v3+v4)/4, a2=(v1+v2)/2−a1 and a3=v1−a1−a2 for the I and Q coordinate values in a first quadrant in the (I,Q) array; computing first and second triples of values defined by and determining a triple of values (B 2x,i B 1x,i B 0x,i ), each value equal to 0 or 1, representing the signal value r x,i in the 64QAM configuration, according to a selected decoding process; and interpreting the triple (B
