Abstract:
The present invention concerns a method and device for demodulating received symbols using a turbo-demodulation scheme comprising an iterative MIMO decoder and wherein an iterative channel decoder is used in the turbo-demodulation scheme, wherein the iterative channel decoder performs a first iterative process named iterative decoding process, the turbo-demodulation performing a second iterative process named iterative demodulation and decoding process, at each iteration of the second iterative process, the iterative channel decoder executing plural iterations in order to decode bits from which symbols are derived from. The iterative channel decoder: memorizes at the end of the iterations of the first iterative process, the variables used internally by the iterative channel decoder, reads the memorized variables at the following iteration of the second iterative process.

Claim (Index 1):
A method for demodulating received symbols using a turbo-demodulation scheme, the received symbols being transferred on plural streams and received through plural antennas, the turbo-demodulation scheme comprising an iterative MIMO decoder decoding the plural streams, a de-interleaving process based on a set of several code blocks of a channel code and wherein an iterative channel decoder is used in the turbo-demodulation scheme for iteratively decoding a channel code, wherein the iterative channel decoder performs a first iterative process named iterative decoding process, the turbo-demodulation performing a second iterative process named iterative demodulation and decoding process, at each iteration of the second iterative process, the iterative channel decoder executing plural iterations in order to decode bits from which symbols are derived, the turbo-demodulation scheme comprises a de-interleaving process based on a set of several code blocks of said channel code, and wherein the method comprises the steps executed by the iterative channel decoder of:\n memorizing at the end of the iterations of the first iterative process, the variables used internally by the iterative channel decoder, receiving, by the iterative channel decoder, a controller message indicating to the iterative channel decoder that the iterative channel decoder has to read the memorized variables at the following iteration of the second iterative process or to reset the memorized variables, the message further comprising the block identifier within the set of several code blocks of the next block to be decoded, reading the memorized variables corresponding to comprise the block identifier within the set of several code blocks of the next block to be decoded at the following iteration of the second iterative process when a message indicating to the iterative channel decoder that iterative channel decoder has to read the memorized variables.
