Color Image Transmission on MIMO MC-CDMA Wireless Communication System.

      Аннотация: Multi Carrier CDMA (MC-CDMA) technique has become increasingly popular in wireless communications, mainly due to its high spectral efficiency, robustness to frequency selective fading and flexibility to support integrated applications. This study incorporates a comprehensive BER simulation study undertaken on the effectiveness of a channel encoded multiple-input multiple-output multi-carrier code division multiple access (MIMO MC-CDMA) wireless communication system on color image transmission. The convolutional channel encoded simulated system incorporates various signal detection techniques such as Minimum mean square error (MMSE) and Zero-Forcing (ZF) and two-dimensional nonlinear order statistic filtering for noise reduction. Simulated results are performed with a color image and the extracted data are processed with different digital modulation schemes under fading channels and AWGN channel with two by two MIMO antenna configuration. The proposed communication system is reasonably acceptable and the applicability of noise reduction technique has improved the image quality significantly.
