【摘要】：频谱资源紧缺已成为限制无线通信技术发展的瓶颈,轨道角动量作为一种新型复用维度,由于其能够实现在同一频率同时传输多路信号,可以有效的提高系统的容量。本文通过对轨道角动量通信系统的误码率进行分析,并在此基础上引入信道编译码,建立了基于轨道角动量的通信系统编译码模型。实验结果表明,高斯噪声环境下,不同调制方式下轨道角动量通信系统误码率与标准通信信道结果相近,相比较2FSK、2PSK而言,轨道角动量通信系统中QAM调制具有更稳定、更优秀的性能。同时,模型中信道编译码的引入为今后轨道角动量通信系统在提高通信系统容量、解决系统模式串扰等方面建立了研究基础。
[Abstract]:The shortage of spectrum resources has become the bottleneck of the development of wireless communication technology. As a new type of multiplexing dimension, orbital angular momentum can effectively improve the capacity of the system because it can transmit multiple signals at the same frequency at the same time. In this paper, the error rate of orbital angular momentum communication system is analyzed, and on this basis, the channel coding and decoding is introduced, and the coding and decoding model of the communication system based on orbit angular momentum is established. The experimental results show that the error rate of the orbital angular momentum communication system is similar to that of the standard communication channel under different modulation modes. Compared with 2FSKK 2PSK, the orbit angular momentum communication system is more stable. Better performance. At the same time, the introduction of channel coding and decoding in the model establishes the research foundation for the future orbital angular momentum communication system in improving the communication system capacity and solving the system mode crosstalk.
