摘要:
PROBLEM TO BE SOLVED: To reduce co-channel interference, in a satellite communication system which each of a plurality of cell clusters, each including at least one cell, includes at least one satellite transmitter for transmitting TDMA signal. SOLUTION: The method includes a step for transmitting time slot of TDMA signal in a first cell cluster at first selected time by a satellite transmitter, and a step for transmitting the same time slot of TDMA signal in a second cell cluster at second selected time by the satellite transmitter. The second selected time is delayed with the selected amount of delay from the first selected time. Consequently, co-channel interference is reduced between the time slot of the first cell cluster and the same time slot of the second cell cluster. COPYRIGHT: (C)2008,JPO&INPIT
摘要(中):
要解决的问题:为了减少同信道干扰,在卫星通信系统中,每个包括至少一个小区的多个小区簇中的每一个包括至少一个用于发送TDMA信号的卫星发射机。 解决方案:该方法包括用于在第一选定时间由卫星发射机在第一小区簇中发送TDMA信号的时隙的步骤,以及用于在第二小区簇中在第二小区簇中发送TDMA信号的相同时隙的步骤 选定时间由卫星发射机。 第二选择的时间被延迟从所选择的第一时间的所选择的延迟量。 因此,在第一小区簇的时隙与第二小区簇的相同时隙之间减少了同信道干扰。 版权所有(C)2008,JPO&INPIT
