Abstract

In this proposed model, performance of different block cipher Modes of operation over ZF channel equalization technique and BPSK modulation scheme in DWT based MIMO Multi-Carrier Code Division Multiple Access (MC-CDMA) system has been analyzed for security issues through simulation. This system is proposed using convolutional coding scheme over AWGN and Rayleigh fading channel with Walsh Hadamard code as orthogonal spreading code. In this research paper, the performance of Electronic Codebook (ECB) mode, Cipher Block Chaining (CBC) mode, Cipher Feedback (CFB) mode, Output Feedback (OFB) mode and Counter (CTR) mode is compared as cryptographic algorithms to encrypt the actual data and decrypt its original form.
