    • The invention relates in particular to a TDMA transmission system including transmitters synchronized to a single receiver, each of the transmitters being able to transmit to the receiver on a given carrier frequency bursts with lengths which are all multiples of that of a unit burst including a guard time, the unit bursts including at least one guard time and the receiver being adapted to receive simultaneously bursts from different transmitters. According to the invention, each transmitter includes means for inserting a filler sequence into each burst to be transmitted at each location of the burst that is likely to correspond to a guard time in a burst received simultaneously on a different carrier frequency. The invention reduces the harmful effects of interference if the time of reception of the guard time of a burst on a first carrier frequency corresponds to the time of reception of information symbols in another burst received simultaneously on another carrier frequency.
    • 本发明具体涉及一种包括与单个接收机同步的发射机的TDMA传输系统,每个发射机能够以给定的载波频率突发发射,其长度与包括卫星的单位脉冲串的倍数相同 所述单元突发包括至少一个保护时间,并且所述接收机适于同时接收来自不同发射机的突发。 根据本发明,每个发射机包括用于将插入序列插入到每个突发中的装置,以在突发中的每个位置处发送,这可能对应于在不同载波频率上同时接收的突发中的保护时间。 如果在第一载波频率上的突发的保护时间的接收时间对应于在另一载波频率上同时接收的另一个突发中的信息符号的接收时间,本发明减少了干扰的有害影响。
