  This paper basically expresses the core fundamentals and brief overview of
the research of R. G. GALLAGER [1] on Low-Density Parity-Check (LDPC) codes and
various parameters related to LDPC codes like, encoding and decoding of LDPC
codes, code rate, parity check matrix, tanner graph. We also discuss advantages
and applications as well as the usage of LDPC codes in 5G technology. We have
simulated encoding and decoding of LDPC codes and have acquired results in
terms of BER vs SNR graph in MATLAB software. This report was submitted as an
assignment in Nirma University
