Abstract
In this project was created a simulation of a radio-communication channel in Simulink (Matlab). It is a graphical tool that allows modeling, simulation and analysis of dynamic systems. The radio-communication channel includes: JPEG coder and decoder, BPSK modulator and demodulator, AWGN channel and some additional boxes to adjust the flow of data. Group of images have been sent through the channel and while changing the parameters of each box the image distortion changes. There were used two subjective methods for image evaluation: DSIS and DSCQS. The methods correlate well. Correlation with the objective methods depended on each method and a type of image distortion. Subjective and objective methods are both equally important for evaluation of image quality
