Efficient Communication Method for Sensor and Sensor Networks

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.
