IWT based image transmission in MIMO-CDMA system: Performance results

Abstract

In this article, we consider the colour image transmission using integer wavelet transform(IWT) coding with the aid of for Multi-input Multi-output (MIMO) - Code Division Multiple Access(CDMA) system over correlated Rayleigh fading channel. IWT is computationally faster and more memory-efficient and hence in our consider work, we implement lossy compression technique based on IWT to achieve sufficient coding efficiency. Further, MIMO system based on Vertical Bell Laboratories Layered Space-Time architecture(VBLAST) is realized both at the transmitter and receiver ends to increase data rate. Furthermore, we consider turbo coded system to achieve better picture quality with less signal-to-noise ratio (SNR) and minimum mean square error (MMSE)-MUD detector at the receiver to suppress noise and Multi-user interferences (MUI). Our simulation study reveals that our considered IWT transform coding technique with MMSE detector achieves better colour picture quality with compression ratio of 4:1 at low level of SNR.
