The invention concerns a method which consists in estimating the discrete symbols (d<k>p) of transmitted signals forming part of the components of a vector D of size N, from a vector Y of a received signal L digital samples, capable of being broken down into Y=AD+YN, where A is a matrix of size LxN previously determined from measurements of at least one transmission channel reply and YN represents a vector of L noise samples. To achieve this, the method consists in determining a greater triangular matrix T of size NxN and a vector Z of size N such that the quadratic criteria PARALLEL TX-Z PARALLEL <2> and PARALLEL AX-Y PARALLEL <2> are minimal for the same vector X of size N, and dividing the vector Z and the matrix T into blocks so as to operate a minimization of the quadratic criterion block by block travelling along the diagonal of matrix T.
