PERFORMANCE EVOLUTION OF COLOR IMAGE TRANSMISSION OVER MIMO WIMAX SYSTEM USING DEFERENT MODULATION

The color image transmission over wireless channel is already explored by many researchers. Due to eye perception for only low frequency component the de-noising technique may be add at receiver end of the wireless device. In this paper, Mobile WiMAX system are used for color image transmission and de-noising method is used for improving the performance. RMSE, PSNR and Spectral efficiency are taken as two parameters for comparing the performance. The multiple input multiple output technique is also used here with the 2x2 antenna systems and QAM-4, QAM-8, and QAM-16 for BER performance improvement. A clear improvement using de-noising technique is found and described in this project.
