| Popis: | The orthogonal coding, which is developed by the author, allows providing the needed communication quality with a smaller power cost. The signal-to-noise ratio’s energy gain is ensured by an effective use of transmitted signals’ power with the unchanged code rate, without an increase of complexity and cost of transmitting and receiving devices. The orthogonal coding is the analogue of convolutional coding over the rational numbers’ field. Properties of orthogonality of proposed codes allow to strengthen the significance of useful signal with simultaneous weakening of the influence of AWGN. Method of the encoding and decoding devices’ design and the example are considered in details. The practical realization of the orthogonal coding has a low level of complexity: each step of the decoding process is technically reduced to a several dot products’ calculation and, consequently, to a contrasting to the zero. For this reason, the offered way of coding and design of encoding and decoding devices can be implemented in various infocommunication systems. |
