This repository presents a MATLAB-based simulation of Bit Error Rate (BER) performance for BPSK and QPSK digital modulation schemes over an Additive White Gaussian ...

Abstract: In this paper, we propose the modified cycle-concentrating progressive-edge-growth (CC-PEG) algorithm for lifting protograph-based quasi-cyclic low-density parity-check (QC-LDPC) codes over ...

Abstract: Modeling and Simulation can play an important role during all phases of the design and engineering of communication systems. Orthogonal Frequency Division Multiplexing (OFDM) was originally ...
