Abstract
The invention relates to a transmission 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, N) of integers (c), the signal transmitted to or from a user consisting of sequences of the same plurality of frames, each integer of said pattern being associated with a corresponding frame and each frame containing a pulse time-shifted from the beginning thereof by an amount (cT) determined by said associated integer, the pulses of one sequence being further position modulated by one or a plurality (n) of data symbols to be transmitted to or from said user. According to the transmission method of the invention, the time at which a sequence of a user is transmitted is obtained from a pseudo-random sequence specific to said user. The invention equally relates to the corresponding transmitter.
