Abstract :
The design of 60 Mbit/s/180 Mbit/s time-division multiple-access (TDMA) channels for the European Communication Satellite (ECS) system is analyzed and a possible configuration is suggested [1]. The effects of adjacent-channel interference, nonlinear power amplifiers both on the ground and in space, uplink and downlink noise are investigated and results are shown. Methods for carrier recovery are investigated and comparisons made. The complete channel design includes pulse-shaping filters, satellite filters, limiters before each TWT, and a filter after the earth-station TWT to limit the radiated spectrum.
