摘要
信道分配是光纤通信系统中的关键技术,当前信道分配方法存在分配错误差、分配速度慢等不足,导致数据传输的误码率高,信号质量差。为了解决当前光纤通信信道分配方法存在的不足,改善提高光纤通信信道质量,提出基于量子粒子群算法的光纤通信信道分配方法。首先对当前光纤通信信道分配方法的研究现状进行深入分析,找到引起光传通信质量下降的原因,然后建立光纤通信信道分配的数学模型,采用量子粒子群算法对光纤通信信道分配的数学模型进行求解,最后仿真测试结果表明,本文方法可以较好防止光纤通信信道之间的冲突,加快了数据传输速度,而且数据传输的误码率低,获得了高质量的光纤通信质量。
channel allocation is one of the key technologies in optical fiber communication systems. The current channel allocation methods have some shortcomings, such as poor allocation error and slow allocation speed, resulting in high bit error rate and poor quality of data transmission. In order to solve the deficiencies of channel assignment method in optical fiber communication and improve the channel quality of optical fiber communication, a channel allocation method based on quantum behaved particle swarm optimization （PSO） is proposed. In depth analysis of the status quo based on the current optical fiber communication channel allocation method, find out the cause of decreased quality of optical communication transmission. And then establish the mathematical model of distribution optical fiber communication channel, using quantum particle swarm optimization mathematical model of distribution optical fiber communication channel to solve. Finally the simulation results show that this method can better prevent conflicts between the optical fiber communication channels, accelerate the speed of data transmission and data transmission. It＇ s error rate is low and it obtains high quality optical fiber communication.
