Detection Schemes for High Order M -Ary QAM Under Transmit Nonlinearities
Quadrature Amplitude Modulation, QAM is a signal in which two carriers shifted in phase by 90
... of imbalances between In-phase(I) and Quadrature-phase(Q) branches in high -order quadrature amplitude modulation (QAM) systems with finite resolution.
As indicated, two controlling signals—known as the in-phase (I) and quadrature ( Q) components—are required to implement complex
