    • 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.
    • 本发明涉及一种数据传输方法和系统,其中用户信号在给定信道中被无线地发送,并且已经为所述系统定义了最大延迟。 该系统包括在发送端的装置(310,312,320),用于顺序执行要发送的信号的外部编码和内部编码;以及用于对外部编码之后的信号执行第一交织的装置(210,212) 在为系统定义的最大延迟的范围内选择所述第一交织的交织长度。 为了确保改进的性能,系统包括用于对内部编码之后的信号执行第二交织的装置(336),所述第二交织的交织长度基本上等于第一交织的交织长度。
