Abstract :
A digital transmission system for global maritime satellite communications has been designed, and experimental communications equipment has been developed, taking account of its potential application to the INMARSAT system where analog modulation is currently used for telephone signal transmission. This paper discusses possible digital technologies to realize an efficient digital transmission system, and presents a concept for the designed system. The paper also describes the hardware configuration and the performance characteristics of the experimental equipment.
