<p>The invention relates to a data transmission method and system wherein the user signals are transmitted wirelessly in a given channel, and a maximum delay has been defined for said system. The system comprises means (310, 312, 320) at the transmitting end for performing sequentially an outer coding and an inner coding to the signals to be transmitted and means (210, 212) for performing a first interleaving to a signal after the outer coding, the interleaving length of said first interleaving being chosen within the scope of the maximum delay defined for the system. To ensure improved performance, the system comprises means (336) for performing a second interleaving to the signal after the inner coding, the interleaving length of said second interleaving being substantially equal to the interleaving length of the first interleaving.</p> |
