A method of communicating data in a system having a plurality of transmitters each adapted to transmit a radio signal, and a receiver situated at a distance from the transmitters to receive and process the signals transmitted by the transmitters, information for transmission being subdivided into N-bit symbols, the method consisting in: giving a numerical value to each symbol; and compressing the data using a CHIP encoding technique in which the values of the symbols are transposed to an encoded value having x digits in a base B, each digit subsequently being represented in the form of n chips, the base B, the number n of chips, and the number x of digits for an encoded value satisfying the following conditions: B≦2&ngr; and 2N≦B&xgr;  so that the total number of chips x.n representing the coded value is less than 2.N.
