摘要
对现场可编程门阵列下通信信息传输效率的优化,可以有效的提升无线通信网络的工作效率。对通信信息的传输效率进行优化,需要通过两个周期相位形成相位判决表,给出FDM信息符号峰均功率比,完成信息传输效率的优化。传统方法结合体数据空间位置信息给出相位旋转因子,计算中相位因子的个数,但忽略了给出信息符号功率比,导致优化效果不理想。提出基于现场可编程门阵列的通信信息传输效率优化方法。利用SLM算法在发送端,并将通信信息嵌入在发送信号中,在接收端,计算信号的模并与相邻两个周期的相位嵌入规则结合形成相位判决表,给出FDM符号峰均功率比,将相邻多个正交频分复用符号的通信信息集中到一个特定符号进行传输,设计出实现正交频分复的系统峰均比抑制模块,完成无线网络通信信息传输效率的优化。实验结果表明,所提方法有效地提升了无线通信网络的传输效率。
An optimization method of transmission efficiency of communication information is proposed based on field programmable gate array. The SLM algorithm is used in transmitting terminal and the communication information is embedded in transmit signal. Then the calculation signal of massive parallel is combined with phase embedding rule of two contiguous periods to form phase decisional table at receiving terminal, and the peak - to - average power ratio of FDM symbol is given. Moreover, the communication information of symbol is used to concentrate adjacent multiple orthogonal frequency division multiplexing in a specific symbol for the transmission, and suppression module of peak - to - average ratio in system is designed to achieve orthogonal frequency division multiplexing. Finally, the optimization of transmission efficiency of communication information in wireless network is completed. Simulation result shows that the proposed method can effectively improve transmission efficiency of wireless communication network.
