Abstract

The article examines the systems of noise-immune coding beginning from linear block codes up to turbocodes. Noise-immunity of these systems is compared with noise-immunity of suggested system of cluster coding. The advantages of suggested system during information transfer in noisy channel are shown. The noise-immunity of the system was determined by modelling in MATLAB environment. It was determined that the threshold level of noise at which the system retains the ability to transfer information depends on the number of readings of carrier wave, which transfers 1 bit of information in a wide range: 50-500. At 500 readings, the threshold noise level is 10 dB, i.e. the power of carrier wave can be lower than the power of noise in communication channel. This exceeds similar properties of the systems used. There is a synchronization scheme of the given system with mark signals application. It was shown that even when the synchronization error occurs, which counts for 80% of the mark signal duration, the system keeps functioning. As a result, the duration of the mark signal can be lower than the duration of the signal, which transfers information bit. This coding system can be applied in ultra-high frequency (UHF) communication channels.
