Abstract:
1. A method for transmitting data symbols to or from users of an ultra bandwidth telecommunication system, each user (u) of said system being associated with a specific time hopping pattern consisting of a plurality (N s , N b ) of integers (c j c ), a signal including said data symbols transmitted to or from a user consisting of sequences of frames, each integer of said specific time hopping pattern being associated with a corresponding frame and each frame containing a pulse time-shifted from the beginning thereof by an amount (c j u T c ) determined by said associated integer, comprising: pulse position modulating one of said sequences by one or a plurality (n based on a pseudo-random sequence specific to said user, determining a time at which said sequence is to be transmitted; time-shifting the time at which the sequence is transmitted from an end of a preceding sequence by a time shift (θ transmitting said sequence to or from said user at the determined time.
