摘要
高带宽传输效率和高边带抑制水平对无线电通信有着重要的意义。该文利用甚小波形差健控(VWDK)已调波形的功率谱结构对其基本波形进行优化,得到带宽更窄、边带抑制更好的VWDK 调制波形。
The high efficiency in bandwidth and high suppression to sidebands are very meaningful for wireless communications. Based on the composition of its modulated waveforms and power spectra, the optimization to very-minimun waveforms difference keying modulations is put forward, and the advanced modulated waveforms with narrower bandwidth and lower sidebands are obtained.
