1. A method, in a transmitter, for transmitting binary data using a M-ASK (Amplitude-Shift Keying) constellation divided into M/2 sets of two symbols, each set of index i comprising the ith and ith+M/2 symbols of the M-ASK constellation, where iϵ[1;M/2], and being associated with a probability pi of transmitting the first symbol of the set and a probability 1−pi of transmitting the second symbol of the set and wherein each symbol of the M-ASK constellation is associated with a binary word defined using natural labelling, said method comprising:
a) obtaining m−1 bits from an equiprobable binary source where m=log2M;
b) selecting a binary source 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;
c) obtaining one bit from the selected source;
d) obtaining a symbol of the M-ASK constellation associated with the binary word formed by the m−1 bits as less significant bits and the bit obtained from the selected source as most significant bit;
e) transmitting said obtained symbol to a receiver over a communication channel.
