摘要

传统的数据传输方法存在着抗干扰能力差的问题,因此在多噪声干扰环境下,提出船舶远程通信数据传输优化方法。首先用无线基站来代替卫星系统实现远程通信设备的更换,在通信数据传输之前对其进行BPSK调制,并对通信环境的噪声数据进行采集,将噪声采集结果作为混合滤波器的阙值进行降噪处理。通过仿真实验发现,在多噪声干扰的环境下传统数据传输方法误码率为12.364%,而优化的传输方法误码率仅为0.312%,由此可以得出结论:优化的船舶远程通讯数据传输方法抗干扰性更强。
        The traditional data transmission method has the problem of poor anti-jamming ability. Therefore, in the environment of multi-noise interference, an optimization method for data transmission of ship remote communication is proposed. Firstly, the wireless base station is used to replace the satellite system to replace the remote communication equipment. BPSK modulation is carried out before the communication data transmission. The noise data in the communication environment is collected, and the noise acquisition results are used as the threshold value of the hybrid filter for noise reduction.The simulation results show that the error rate of the traditional data transmission method is 12.364% in the environment of multi-noise interference, while that of the optimized method is only 0.312%. Therefore, it can be concluded that the optimized method of ship remote communication data transmission has stronger anti-interference ability.
