针对当前的直接序列扩频传输方法误码率较高的问题,提出基于吸收系数的光纤通信网络突发数据传输模型。论证信道吸收系数与突发数据传输频率的关系,结合吸收系数的理论,采用匹配滤波检测器进行码间干扰抑制,实现突发数据传输的空间增益聚焦,减小信道误码的影响。仿真结果表明,采用该算法进行光纤通信网络突发数据传输,能有效抑制码间干扰,降低突发数据传输过程中的通信误码率,信道均衡性能也得到了较大的改善。
Aiming at the problem of the high bit error rate (BER) of the direct sequence spread spectrum transmission method, a burst data transmission model of optical fiber communication network based on absorption coefficient is proposed. The relationship between channel absorption coefficient and burst data transmission frequency is demonstrated. Based on the theory of absorption coefficient, matched filter detector is used to suppress intersymbol interference, to achieve spatial gain focusing of burst data transmission and reduce the impact of channel error code. The simulation results show that the algorithm can be used to transmit burst data in optical fiber communication network, which can effectively suppress intersymbol interference and reduce the bit error rate in the burst data transmission. The channel equalization performance has also been greatly improved.
