| 摘 要： | 数字式调制与许多模拟调制方式相比,在相同的信噪比条件下误码率低.基于BPSK编码方式和微弱信号检测及单片机技术,针对光在大气通信中遇到的实际困难,提出了一种低信噪比条件下的点对点通信实验方案.该方案发送数据的相位精度高,可控性好,接收端前置放大器动态范围宽,解码能力强.

| Abstract: | Digital modulating has many advantages by comparison with the analog modulating,and has low bit error rate (BER)under the same SNR.A new scheme is developed which is designed for optical wireless communication,based on BPSK,weak signal detection and MPU.The scheme is available for point to point communication,with characteristic of high phase precision data,wide dynamic range and great decoding ability.The results of this experiment show that this scheme is feasible. |
