Quality estimation of data transmission is a high priority goal of data transmission systems research. Estimation from the side of used error-correcting schemes efficiency can be one of the solutions. In this paper we would like to show the results of the comparison of error-correcting schemes in T-DMB and DAB protocols in conditions of data transmission between moving subscribers. These results are represented as a graph of dependence probability of error from Signal-to-Noise ratio and show the gain when using T-DMB for transmission of multimedia services in mobile channels. We show that using T-DMB for data transmission in the mobile channel can provide high quality transmission. NCTUns implementation model was used during this work.
