Abstract

The demand-assigned time division multiple access (DA-TDMA) system has remarkable advantages with regard to effective utilization of satellite traffic channels and network flexibility; it is one of key technological developments for application to integrated services satellite digital networks (ISSDN) which transmit digitally integrated information signals between Earth stations. The experimental DA-TDMA system designed for an ISSDN experiment has a 20 Mbps bit rate and operates in a fully variable demand-assignment mode. This experiment is planned as the first stage of ISSDN study in Japan and its objective is to confirm that various service networks are possible with satellite communications in which various information signals are digitalized and integrated for communication between Earth stations.
