A method for transmitting binary data using a M-ASK constellation divided into M/2 sets of two symbols is disclosed. Each set of index i comprises the iand i+M/2 symbols of the constellation and is associated with a probability pi of transmitting the first symbol of the set. First, m−1 bits are obtained from an equiprobable binary source where m=logM. A binary source is then selected in a plurality of binary sources responsive to said m−1 bits, each binary source of index i being associated with a probability of outputting a bit zero equal to pi. A symbol of the M-ASK constellation is obtained that is associated with the binary word formed by the m−1 bits as less significant bits and a bit obtained from the selected source as most significant bit. The symbol is finally transmitted to a receiver over a communication channel.
