- One of the ways to improve track circuits is associated with transfer of equipment to modern microelectronic element base and with using new more advanced signal processing techniques. In paper the various methods to improve interference immunity of tonal track circuits have been considered. It was proposed instead of periodic amplitude shift keying signals use the phase shift keying signals with six-bit Hamming code. This will allow to expand the number of selective marks and to increase the information redundancy of signal. As a result, the probability of correct detection of such signal under influence of interferences will increase. The expedience of using the correlation demodulation with receiving code combination by symbols also has been shown. The efficiency of proposed methods is confirmed by the results of simulation.
