Paper Abstract

A computer simulation of DPSK and PSK transmission systems has highlighted several parameters that critically affect system performance. The simulations reveal that, in practice, PSK systems can be made to operate closer to their ideal detection sensitivity than DPSK systems. These findings are supported by experimental measurements. A PSK system was assembled using a travelling wave laser amplifier repeater, the addition of which caused no significant degradation of receiver sensitivity. The experiment confirms the suitability of laser amplifiers for coherent systems.
