The growth of modern wireless communications has increased the demand for high quality and reliable data services. The purpose of this article stands for a review of the principles and techniques of error correcting codes (ECC) and a study of their practical application to combat intersymbol interference (ISI) in multipath channels. A DVB-T system with MIMO technology developed in the Matlab/Simulink environment is introduced and analyzed. The bit error rate (BER) of the additive white Gaussian noise (AWGN) channel and an ISI-influenced multipath Rayleigh attenuation channel is measured and discussed. The method based on a DVB-T receiver-transmitter with MIMO technology provides a higher quality and speed of data transmission in comparison to a DVB-S2 system with MIMO. Other ways to improve the quality of data transmission are offered, including size and type converters, amplifiers, and gain normalization. Images are transmitted through the system that includes a Rayleigh channel and an AWGN with different signal-to-noise ratio values (SNR, dB) and different gain values. The BER graph is obtained; the results are discussed and compared with similar works. The system can be used for transmission of radiological images (such as computed tomography or magnetic resonance imaging) of high quality and high resolution to remote healthcare workers using a wireless network.
