Secured Text Message Transmission in Pre -Channel Equalization Based MIMO- OFDM System With Implementation of Concatenated ECB and CFB Cryptographic Algorithm

In this paper, the authors made a comprehensive performance evaluative study of a secured MIMO orthogonal frequency-division multiplexing wireless communication system with implementation of two pre-channel equalization techniques such as Pre-Minimum Mean Square Error (Pre-MMSE) and Pre-Zero Forcing (Pre-ZF) under QPSK and QAM digital modulations. The simulated system deploys three channel coding techniques (1/2-rated Convolutional, CRC and BCH). In the present simulated system, text message transmission has been secured with concatenated implementation of Electronic CodeBook (ECB) and Cipher FeedBack (CFB) cryptographic algorithm.
