摘要：
This paper gives an insight on, error control codes, where Low Density Parity Check (LDPC) codes or turbo codes are used to encode the data stream to tolerate channel errors and triple encryption is done to prevent un-authorization before passing the data over Orthogonal Frequency Division Multiplexing (OFDM) system. The system adopts diverse modulation schemes like Binary Phase Shift Keying(BPSK), Quadrature Phase Shift Keying(QPSK) and Quadrature Amplitude Modulation(QAM) using Additive White Gaussian Noise (AWGN) channel. The comparative analysis of LDPC over turbo codes is done and Bit Error Rate(BER) Vs Eb/No values are plotted and correlation values are computed after encryption.
