【摘要】 研究了不同程度啁啾分量高斯形光脉冲信号对带前置放大器光接收机灵敏度的影响,同时进行了理论分析和数值摸拟。发现适当选取高斯形光脉冲信号归一化相对脉宽因子、啁啾分量、接收机均衡滤波器输出的升余弦频谱波形滚降因子的值可以提高光接收机灵敏度,其结果对实际光接收机的分析和设计有一定指导意义。更多还原

【Abstract】 Effect of gauss light pulse with chirp on sensitivity of receiver with optical preamplifier is discussed. It is found that the α,β and c to be adequately valued will improve the sensitivity of receiver. Theonetical analysis is done and the correspond carve is worked out. The result provides a significant reference for design of receiver.更多还原
