Abstract

in spectrum and energy limited cases, efficient communication methods are attractive. First, the article presents EBPSK based UNB modulation method including opEBPSK and MEBPSK modulation, and then frequency domain window filter design is studied, which shows a sharp sideband attenuation and a narrow noise round off characteristics, last, a simulation is done based on the (op)EBPSK and MEBPSK modulation using the frequency domain window filter, and the results show that a good spectrum and energy efficiency using measure of the noise bandwidth and bps/Hz/SNR, especially, for MEBPSK, it has a better SER and BER, when SNR is larger than -4dB, the BER even approaches the ideal BER with infinite bandwidth.
传感器和传感器网络的有效通信方法
在频谱和能量有限的情况下,有效的通信方法是有吸引力的。本文首先介绍了基于EBPSK的UNB调制方法,包括opEBPSK和MEBPSK调制,然后研究了频域窗滤波器的设计,该方法具有明显的边带衰减和窄的噪声舍入特性,最后,对基于(op)EBPSK和MEBPSK调制的频域窗滤波器进行了仿真,通过测量噪声带宽和bps/Hz/信噪比,结果表明EBPSK和MEBPSK调制具有良好的频谱效率和能量效率。对于MEBPSK,它具有更好的SER和BER,当信噪比大于-4dB时,BER甚至接近无限带宽下的理想BER。
