Abstract: This study investigates the performance of Chaotic Baker Map and Double Random Phase Encoding (DRPE) encryption schemes in comparison with wireless communication channel. A comparison is drawn between the discrete Fourier transform (DFT)-orthogonal frequency-division multiplexing (OFDM) system on one hand, and the discrete wavelet transform (DWT)-OFDM system and the discrete cosine transform (DCT)-OFDM system in an additive white Gaussian noise (AWGN) environment on the other.  The Haar wavelet and quadrature phase shift keying (QPSK) modulation format are also considered. The study includes detailed mathematical calculations designed to measure the peak signal to noise ratio (PSNR) of two encryption schemes over OFDM system on AWGN channels. The results obtained through these simulations demonstrate clearly that the DFT-OFDM system yields the best performance.
