摘要 光在大气中传播时,由于受到复杂的气象条件的影响,实际上接收机接收到的信号是一个随机信号,在时间和空间上都有一定相关性。对大气强抖动和弱抖动模式下空间光信道衰减模型做了深入分析,并用似然检测分析了系统性能。 When laser transmits in atmosphere, the factually received signal is a random variable, which has the coherence in time and space. The model of the optical channel in strong and weak turbulences is analyzed, the system performance is studied by maximum probability detection.
