Abstract
The present invention concerns a method for decoding differentially modulated received symbols, the differentially modulated received symbols corresponding to a transmission of a differentially modulated version of a codeword out of a set of possible codewords, the received symbols being transferred onto resources of a channel, the resources being equally spaced. A receiver, for each possible codeword: - obtains a vector of differentially demodulated symbols by differentially demodulating the differentially modulated received symbols obtained by combining two consecutive differentially modulated received symbols, - calculates the product of each differentially demodulated symbol by the conjugate of the element of the codeword having the same rank within the codeword as the differentially demodulated received symbol, - calculates the module of the sum of the products, - decodes the vector of differentially demodulated symbols by selecting the codeword for which the module of the sum of the products is the maximum.
