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。
Aiming at the problem of high bit error rate and large communication distortion in laser communication system, the optimization of laser communication system is proposed based on multipath radiation channel equalization and inter-symbol interference suppression, and the relationship between the radiation and the bit error rate of laser communication system is studied. By reducing the radiation interference and improving the communication performance, a multipath channel model of the laser communication system is constructed, the radiation intensity of the channel is measured, and an adaptive equalization technique is used to suppress the inter-symbol interference in the laser communication system, so that the laser communication symbol is transmitted in every frame The signal time to maintain a relatively stable channel, thereby reducing the communication error rate. The simulation results show that the laser communication system designed by this method has lower bit error rate and improved the communication quality of the laser communication system.
