Abstract
Introduction. The introduction describes the main characteristics of bit errors. These sources of bit errors in discrete channels. Also listed scientists who worked on the study opportunities monitoring bit error in discrete channels. The main purpose of the article is to conduct research and theoretical modeling of processes in discrete channels to control error measurement and forecasting parameter BER bit error depending on the signal/noise ratio. Theoretical analysis. A comparison of some types of digital modulation for effective use in systems transmitting information. Comparisons were made using the correlation function, power spectral density and distance between signals. It was proved that through this you can control the real value of bit error (BER) for each type of modulation. Important here is the dependence of the BER signal/noise ratio in the test communication channel. Determined that efficiency could be described bit error probability value of the output of the receiver, which is determined by the expression (4). Control parameters BER modulation in digital signals. At this paragraph the examples of control parameter BER at different modulation signals. The simulation results show that with an increase in the signal/noise bit error probability for different types of demodulation will decrease.
