摘　　要：受通信业务量激增的影响,串行通信网络的吞吐量急剧下降,为此提出基于Nutaq平台的串行通信分组轮询多址接入方法。借助Nutaq平台利用信道容量接收矢量,得到通信网络接收串行信号的协方差矩阵,根据信息熵与条件熵之间的联系,计算通过串行通信网络所输出的分组轮询多址概率分布,再利用编码函数映射过程得到译码函数,计算信道码的均衡误差概率。根据计算结果设计串行通信分组轮询多址接入算法,实现了串行通信分组轮询的多址接入。仿真结果表明,与传统方法相比,所提方法在信道带宽为20MHz、80MHz和160MHz时,串行通信网络吞吐量均得到了明显提高,充分验证了该方法的应用效果。The increase of communication traffic leads to the decrease of throughput of serial communication network.Therefore,this paper presents a packet polling multiple access method based on Nutaq platform.With the use of Nutaq platform and channel capacity,vectors were received to obtain the covariance matrix of serial signals received by communication network.Based on the relationship between information entropy and conditional entropy,the probability distribution of packet polling multiple access output by serial communication network was calculated.The coding function mapping process was adopted to obtain the decoding function and the equalization error probability of the channel code was calculated.A packet polling multiple access algorithm for serial communication was designed to achieve the multiple access of serial communication packet polling by the calculation results.The simulation results show that the throughput of serial communication network is greatly improved at the channel bandwidths of 20 MHz,80 MHz and 160 MHz,which implies that the method has excellent application effect.
