Analysis of relationship between bit error rate and radiation of laser communication system

针对激光通信系统误码率较高,通信失真较大的问题,基于多径辐射信道均衡与码间干扰抑制,提出激光通信系统优化技术,研究辐射与激光通信系统误码率间的关系。通过降低辐射干扰,提高通信性能,构建激光通信系统的多径信道模型,测量信道的辐射强度,对激光通信系统的码间干扰采用自适应均衡技术进行干扰抑制,使得激光通信码元在每帧信号时间内信道保持相对稳定,从而降低通信误码率。仿真结果表明,采用该方法进行激光通信系统设计,误码率较低,改善了激光通信系统的通信质量。

For laser communication system bit error rate is higher, communication distortion is a big problem, proposed optimization techniques based on multi-path channel equalization radiation and intersymbol interference suppression of laser communication system, relationship between on the radiation and laser communication system bit error rate to construct the multi-path channel model of laser communication system, the radiation intensity of the measuring channel, to the code in the laser communication system interference between the adaptive equalization techniques for interference suppression, making laser communication symbols in each frame time signal channel remained relatively stable, so as to reduce the error rate of communication. Simulation results show that the method is used to design the laser communication system, and the bit error rate is lower, improve the communication quality of the laser communication system.
