摘要
为了满足毫米波通信中千兆宽带传输的需求,在现有硬件平台处理能力基础上,针对调制解调器中的并行定时同步算法展开研究。设计了系统的数据帧结构,提出了并行数字滤波平方算法,分析了数据帧长对采样时钟稳定度的要求,结合工程实现提出了简化方法和实施方案,利用Matlab软件对AWGN信道下性能进行仿真。仿真结果和实际应用表明,所提出的算法可有效提高系统的数据处理速度,且适用性广。
In order to meet the needs of Gbit level high-speed data transmission of millimeter-wave communication,on the basis of present hardware platform processing capability,this paper studies the parallel symbol timing synchronization.The data frame structure of system is designed,the parallel digital filtering and square timing recovery algorithm is proposed and the requirements of data frame length on sampling clock stability is analyzed.Combining with the engineering implementation,the simplified method and implementation scheme are proposed.The simulations are performed for system performance under AWGN channel using Matlab software.The results and practical application show that the parallel symbol timing synchronization algorithm can effectively improve data processing speed of the system,and has wide applicability.
