FIELD: radio engineering, communication.SUBSTANCE: transmitter encodes information into a stream of binary bits and groups of bits are combined to be represented by data symbols. Then, each data symbol is represented by a set of coordinates in a multidimensional space, where the number of dimensions in the multidimensional space corresponds to at least three orthogonal components which will contain the transmitted radio signal. The coordinates of each data symbol are chosen such that each data symbol is located at a minimum distance away from the nearest other data symbol in the multidimensional space and also such that the peak amplitude to root mean square amplitude of the transmitted radio signal is minimised.EFFECT: generating a radio signal with a reduced peak amplitude to root mean square amplitude ratio, which improves transmission efficiency of the power amplifier of the transmitter.21 cl, 17 dwg, 4 tbl |
