Abstract (en)
[origin: WO2007028834A2] The invention relates to a method of improving the iterative decoding of short codes in a demodulator. The inventive method is characterised in that it comprises at least the following steps consisting in: decoding the bit metric vector output from the demodulator; comparing the value of the check code of the CRC of the decoded word with a pre-determined value; if the value of the CRC forms an acceptable message for the decoding step, transmitting the decoded word to the recipient; and, if the value of the CRC is incompatible with a correctly-decoded message, modifying the iterative decoding parameters of the initial message, which were received from the demodulator, and executing at least one new iterative decoding step with said new parameters.
