Abstract:
A transceiving system using a joined modulation alphabet A having a size M the symbols of which are distributed on a plurality N of orthogonal dimensions, the symbols carried by a dimension belonging to a linear sub-alphabet A n  having a size P, with M=NP. The transmitter performs a turbocoding of a block of information bits, the code words provided by the turbocoder being mapped to symbols of the joined modulation alphabet before modulating the signal to be transmitted. The receiver performs turbodecoding from the projection of the symbols received on the orthogonal dimensions of the alphabet.

Claim (Index 9):
A receiver for receiving a signal transmitted by the transmitter according to  claim 1 , the signal received by the receiver being base-band demodulated to provide a block of successive received symbols, the receiver comprising a series-parallel converter receiving the successive received symbols and providing them to a plurality K of parallel branches, the receiver being characterised in that each branch (l) comprises a detection module adapted to project a symbol (y l ) received on this branch onto the N orthogonal dimensions of the modulation alphabet A to obtain a vector having N components (Y 0 l , Y 1 l , . . . , Y N\u22121 l ) and deduce therefrom as a word having NP soft values the logarithm of the observation probabilities (log [p(y l |x k )]) of the received symbol assuming that the different symbols of the modulation alphabet have been transmitted, the detection module providing the words thus obtained to an elementary decoder, the elementary decoders of the different branches being chained together so as to perform turbodecoding, the turbodecoding providing probability logarithmic ratios, called LR values, for the different information bits of the block, the information bits of the block being estimated by a hard decision on the LR values thus obtained.
