Efficient Wireless OFDM for Secure Force Encryption Algorithm Images
Security one of the important features in wireless communication is very crucial to protect information of the subscribers and avoid fraud. This paper is to look into the influence of Gaussian, Rayleigh fading channel and low computational complexity to the performance of various types of the OFDM as the fast Fourier transform (FFT) based orthogonal frequency division multiplexing (OFDM),the discrete cosine transform (DCT) based OFDM and the discrete wavelet transform (DWT) based OFDM of the wireless of the Secure Force (SF) encryption algorithm images. Zero Forcing (ZF) equalization and simple filters are utilized in this paper as a tool to enhance the communication system performance. Two well-known performance criteria: Mean Square Error (MSE)and Peak Signal Noise Ratio (PSNR) to evaluate results.
