INTEROFFICE PHASE SYNCHRONIZATION SYSTEM AND INTEROFFICE PHASE SYNCHRONIZATION METHOD

摘要

In a TDMA communication system having one masterstation and a plurality of slave ststions, phasesynchronization of output frame phases between slavestations is established with quite simple construction.In the master station, a super frame consisted of aplurality of standard frames is generated in the superframe generating portion. In the master station, using atiming position matching loop already existing between themaster station and the slave station, signal delay periodbetween the slave station and the master station isderived. The delay period is transmitted superimposing onthe frame in the super frame period. In the slave station,half period of the delay period defined by the delayinformation is calculated. The super frame is delayed forthe corresponding period to out to the next stage servicearea. By this, phase of the super frame is synchronizedbetween all of the slave stations.
