摘　　要：从激光对潜通信的能量传递模型出发讨论改善接收机性能的方法,分别针对背景辐射、光脉冲时域和空域的扩展和光斑强度的随机变化引起的信号衰减、畸变、起伏等影响通信质量的因素展开分析。本文对上述因素提出了改善措施,并且提出了将动态自适应调节系统应用到分集接收系统中,提高接收机的性能。This paper expounds and improves the performance of receivers on the foundation of energy transfer model of submarine laser communication （SLC）. The paper thoroghly analyzes the signal attenuations, signal distortions, signal fluctuations, and other factors affecting the communication quality. The affecting factors are caused by background radiation, the light plus expansion from the time and airspace, and the random change of the light plus strength. The paper proposes some improved measures to those factors above mentioned, applies the adaptive adjusting system into diversity reception system, and advances the performance of receivers.
