摘要
为了实现海洋可控源甲板监控系统中数据传输的同步,采用了OFDM传输系统,重点研究了基于OFDM原理的ML算法。在此基础上,加入了迭代,形成ML迭代算法。此算法具有计算量小,冗余度低等优点。经测试,频谱搬移控制在0.5%以内,达到海洋可控源甲板监护系统的要求,实现了数据传输的同步。
In the marine controlled source deck monitoring system,in order to achieve synchronization of data transmission,the OFDM transmission system focuses on the study of ML algorithm based on OFDM principle,on this basis,joins the iteration,ML iteration algorithm.This algorithm has small computation,low redundancy,etc.After testing,the spectrum shifting is controlled within 0.5%,which can achieve the requirement of marine controlled source deck monitoring system and realize the synchronous data transmission.
