Method for the optimisation, under resource constraint, of the size of blocks of coded data

摘要

Method of optimising the size of blocks of coded data, intended to be subjected to iterative decoding, the method comprising a first step evaluating a resource (T) available for the decoding of a block of normal size (N) and a second step seeking, amongst a plurality of block sizes (N/k) which are submultiples of the normal size by an integer factor (k) greater than or equal to 1 and requiring on average a number of iterations ({overscore (n)}_iterations) compatible with the said available resource, the one which makes it possible to obtain the lowest error rate at the output of the iterative decoding.
