It is difficult to study the characteristics of high speed optical communication system due to the complexity and high-cost in configuration. In this paper, aiming to overcome the weakness above, the performance of a 10Gbps optical communication system with single channel is investigated by simulation. Then, based on the outputs of RZ and NRZ codes modulated, an extensive comparison is developed in terms of spectrums, noises, eye diagrams and bit error rate.

Atmosphere Turbulence

The satellite-to-ground optical communication system suffers from atmosphere turbulence severely. It is well-known that the coherent detection can increase the receiver sensitivity and performing aperture averaging can reduce the scintillation caused by the atmosphere turbulence. In this paper, the bit error rate, the outage probability and the average capacity of a coherent satellite-to-ground optical communication downlink with aperture averaging are analyzed. The Log-normal atmosphere turbulence model and BPSK (Binary Phase Shift Keying) modulation is employed. The analyzing focuses on the improvement of aperture averaging with different atmospheric conditions and zenith angles of the satellite. The bit error rate performance based on measuring data is given too. The results demonstrate the bit error rate and the outage probability can be reduced and the average capacity can be improved by aperture averaging efficiently. When the turbulence is stronger and the zenith angle is larger, the effect of aperture averaging is more obvious. The aperture averaging effect on BER (Bit Error Rate) is better than the effect on average capacity.

In this paper, a model of FH spread spectrum communication system has been built in Matlab/Simulink platform. Theoretical analysis of repeater jamming are derived. These limitations arise because of the geometry and so on. Then, we analyze the bit error rate performance in FH communication system under repeater jamming. The benefits of frequency hopping are potentially neutralized by a repeater jammer.
