Abstract:
Process for the processing of a signal corresponding to a direct sequence spread spectrum information transmission through a multiple path channel, said process being characterized in that it comprises the following operations:a) a correlation is performed between the signal to be processed and the direct sequence used, which supplies several correlation peaks of different amplitudes, b) the highest amplitude correlation peak is determined and the corresponding information restored, c) the spectrum of the information corresponding to the highest amplitude peak is respread using the same direct sequence, d) from the signal to be processed is subtracted the part corresponding to said respread information and a new signal is obtained, e) operations a, b, c and d are reiterated for said new signal and so on until the peaks are exhausted, f) on the basis of the different informations successively obtained for the different correlation peaks, the transmitted information is restored.
