The objective of the article consists in a development and a research of the offered by the author orthogonal coding as a way of noise immunity’s increase using the example of the information communication systems with phase-shift keying. It is shown, that the orthogonal coding allows to provide the required quality of communication with a smaller energy cost. The energy gain in signal-tonoise ratio (up to 6,4 dB in the channels with the AWGN, up to 22,74 dB in the fading channels) is provided by more effective use of energy of transmitted signals without increase in complexity and cost of transmitting/receiving devices.The procedure of harmonization of symbols of an orthogonal code with phase-shift keying is developed. The main attention is paid to a problem of synchronization of signals in combination with orthogonal codes.
