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: 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 ...

Abstract: Recently one decoding algorithm called as beyond belief propagation (BP) algorithm for LDPC Codes is derived using the knowledge of trapping set and different from standard BP algorithm, ...
