In this article the propagation of a radio signal and the methods of its processing and transmission, which reduce the number of bit errors and increase the noise immunity of a data transmission system are studied. The main aspects of model-oriented design and simulation modeling are considered. In this work the MatLab code for the OFDM method of processing a radio signal are used. Dependency graphs explaining the effect of the impacting interference on the propagated signal are obtained. During the simulation, models of MIMO-OFDM systems using a radio channel for quadrature amplitude modulation types 64 and 16QAM are described.
Keywords:OFDM system, radio signal, amplitude modulation, MatLab Simulink, convolutional coding, MIMO, Gaussian noise, error probability coefficient BER
