VWDK: Just an illusion?

摘要

摘要: 为验证VWDK调制方式高频谱利用率特性，该文先介绍了VWDK调制的基本概念，然后对其调制与解调的进行了仿真验证，仿真结果证明其超窄带并不是通常意义下的窄带传输。进而又从理论推导得到该种调制方式的功率谱，并对其功率谱的能量分布进行了分析，对其高效频谱利用率提出了质疑。

Abstract: To verify the high spectral efficiency of VWDK, the principle of the modulation is introduced in detail. The simulation results of VWDK modulation and demodulation confirm that UNB is not what is generally called. Moreover, through calculating the analytic formula of its power spectrum, and analyzing the distribution of its spectra power, the so called high spectral efficiency of VWDK is just an illusion.
