In this paper we consider perfect codes over two dimensional QAM-type constellations of any cardinal. Such constellations are going to be modeled by L-graphs, ...
Bibliographic details on Graph-based metrics over QAM constellations.
Dec 26, 2020 · What you typically want to plot is the baseband signal, the RF after it is filtered, mixed against the carrier wave, and coherent (phase-locked).

Apr 10, 2023 · QAM (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 ...
The Constellation Diagram block displays real- and complex-valued floating- and fixed-point signals in the IQ plane.
Feb 29, 2024 · This makes QAM constellations desirable for soft decoding; and that has more advantage over hard decoding (i.e. after your constellation ...
Apr 15, 2022 · In this research article, a novel modulation classifier is presented to recognize M-Quadrature Amplitude Modulation (QAM) signals using random graph theory.
