Optical Communications: 64-QAM classification with neural networks. Investigating the performance of an OFDM-based communication system with QPSK and QAM modulation and effects of AWGN and multi-path ...

Abstract: The presented research examines Quadrature Amplitude Modulation (QAM) using MATLAB. QAM can be defined as a popular modulation approach that is used today by many communication systems for ...

MATLAB project implementing a 64-QAM baseband link simulation over an AWGN channel, with optional nonlinear RAPP PA model. The repo includes modulation/demodulation, Gray mapping, BER/BLER evaluation, ...

In this paper, the authors introduce the Bit Error Rate (BER) simulation using 16 QAM (Quadrature Amplitude Modulation) in Matlab. Bit error rate is used to assess systems which can transmit digital ...

Half the bits are represented on the real axis and half the bits are represented on the imaginary axis. The in-phase and quadrature signals are independent level Pulse Amplitude Modulation (PAM) ...
