<p>The invention relates to a CDMA transmission system comprising at least a transmitter in which a data sequence is spread with a code sequence, and comprising at least a receiver in which the data sequences are recovered by means of a detector. To load only the frequency portion used having the necessary frequency bandwidth in CDMA transmission systems, a frame structure is proposed in which the payload to be transmitted in a frame is compressed to a signal burst. A burst in a frame is then characterized by a frame-relative initial instant to and a dedicated duration ta.</p> |
