【摘要】：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。
[Abstract]:Aiming at the problems of high bit error rate (BER) and large communication distortion in laser communication system, based on the multipath radiation channel equalization and inter-symbol interference suppression, the optimization technology of laser communication system is proposed to study the relationship between radiation and BER of laser communication system. By reducing the radiation interference and improving the communication performance, the multipath channel model of the laser communication system is constructed, the radiation intensity of the channel is measured, and the interference suppression of the inter-symbol interference of the laser communication system is carried out by adaptive equalization technique. The channel of the laser communication symbol is relatively stable in each frame signal time, thus reducing the bit error rate (BER). The simulation results show that the error rate of the laser communication system is low and the communication quality of the laser communication system is improved by using this method.
