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 ...

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 ...

Abstract: This paper presents a performance evaluation approach using the BERTool module provided under Matlab/Simulink software package. It compares different ...

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) ...
