WebApr 11, 2024 · We propose and experimentally demonstrate a novel scheme to generate ultrahigh-order frequency multiplied millimeter-wave (mm-wave) signals with high fidelity enabled by angle modulation (ANG-M). The constant envelope (CE) characteristic of the ANG-M signal makes it possible to avoid nonlinear distortion induced by photonic … WebQAM (pronounced "kwom") stands for Quadrature Amplitude Modulation. It is a way of modulating, or changing a waveform, called a carrier wave, to encode the 1's and 0's that make up the data you wish to transmit across the RF (Radio Frequency) medium. This is done by manipulating the phase and amplitude of the carrier wave.
