摘要
在多网融合平台技术基础上,提出了一种短波-GPS海事通信网络,对系统中的关键设备基于OFDM的短波并行调制解调器进行了研究设计,给出了具体实现方法。对GPS伪码测量的多径误差进行了分析,给出性能仿真结果,为克服GPS测量中的多径误差提供了理论依据。
A scheme of HF-GPS maritime communication networks is proposed,which is based on multi-network convergence.The key device of HF parallel modem based on OFDM in the system is studied and implemented.The multi-path error for GPS code measurement is analyzed,and the simulations are obtained,which can provide theory evidence in the work to overcome the multipath error in GPS measurement.
