“…It was assumed that a poor demodulated signal of pulse shape and hence closure of the "eye", would lead to a poor error performance; a closure of 10% in pulse amplitude corresponds to <0.5dB penalty. 4.SIMULATION RESULTS Fig 3 shows a simulation of an ideal DPSK system when data rate = carrier frequency. This displays the phase, the resulting IF after detection and the recovered pulse shape after demodulation.…”

A computer simulation several parameters that reveal that, in practice, detection sensitivity than measurements. ABSTRACT of DPSK and PSK transmission systems has highlighted critically affect system performance. The simulationsPSK systems can be made to operate closer to their ideal DPSK systems. These findings are supported by experimental 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.
