Abstract :
The authors focus on the digital implementation and performance of a multipath fade tolerant, differentially coherent, 8-PSK based modem. At the receiver, differential detection using a novel matched filter arrangement, and feed forward Doppler compensation is employed to achieve many operational benefits. For this demanding L-band satellite link, the channel utilization is an efficient 1.0 bps/Hz for raw data and 1.5 bps/Hz for coded data
