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. The orthogonal coding is an analogue of convolutional coding over the rational numbers’ field. Properties of orthogonality of proposed codes allow to strengthen significance of useful signal with simultaneous weakening of influence of noise. The orthogonal coding allows to provide the required quality of communication with a smaller energy cost. The main attention is paid to an actual problem of synchronization of signals in combination with orthogonal codes.
