    Anti-fading technology of near space communication based on quasi-constant envelope OFDM by Yang LU, Donglei ZHANG, Tingting WANG

    Published 2019-01-01
    “…An anti-fading technology of near space communication based on quasi-constant envelope OFDM (QCE-OFDM) was proposed. At the transmitting end, two OFDM signals were respectively modulated on the phases of two constant envelope signals, and then they were merged into one signal via phase shift. …”
