基于DRM信号的短波探通一体化技术
Integration technology of HF communication and channel detection based on DRM signal
摘要
Abstract
HF communication is always considered as an important way of wireless remote communication.The purpose of this paper is to reduce the bit error rate (BER) by using an integrated signal with communication and detection function to detect HF channel characteristics in real time and use the detection results to correct the signal itself while HF communication is carried out simultaneously.The digital radio mondiale (DRM) signal is chosen as the integrated signal.After analyzing the detection performance of the signal,an algorithm for detection of integrated signals is constructed to achieve the correction of integrated signal and improve its communication performance by constructing deconvolution filters using the channel characteristic(time delay,Doppler frequency shift,relative attenuation) parameters detected.Finally,the simulation results show that compared with the traditional HF communication method,the proposed algorithm not only improves the bandwidth utilization,but also reduces the communication bit error rate,and has a good performance.关键词
