Abstract
A method and a device are described for determining data from a signal spread over at least one frequency base band representing the data. The method for generating a signal has a step of using at least one highly auto-correlated spread code sequence (1C, 2C) associated with the frequency base band for determining a delay with which a modulated portion (1P, 2P) of the data is spread on the signal. The method has further steps of determining said modulated portion from the signal using the delay and the spread code sequence (1C, 2C), of demodulating the modulated portion (1P, 2P) using phase shift keying, and of determining a remainder (1R, 2R) of the data using the delay.
