Claim Text:
1. A method for transmitting symbols of non-binary error-correcting code words via a single carrier system, each code word symbol comprising p bits, wherein p is an integer greater than 0, said method comprising: a first modulation step associating each p-bit code word symbol with a sequence of at least 2 a second modulation step to modulate a phase or amplitude of a single carrier signal with sequences associated with the non-binary error-correcting code words and generate modulated symbols having a size equal to a size of the sequences associated with the non-binary error-correcting code words, and a transmission step for transmitting the modulated single carrier signal via said transmission channel, wherein the first modulation step is a spread spectrum modulation of a cyclic code-shift keying type using a basic pseudo-random sequence of at least 2
