MANIPULATION CODING OF SIGNAL OF N-DIMENSIONAL MULTI-POSITION CONSTELLATIONS ON THE BASIS OF OPTIMAL BY NOISE IMMUNITY REGULAR STRUCTURES
Journal Title: Телекомунікаційні та інформаційні технології - Year 2017, Vol 130, Issue 3
Abstract
An urgent issue today is the introduction of mobile broadband access equipment on the telecommunications network of the fourth and fifth generation (LTE). In this paper, we consider methods for the optimal inscribing of signal regions. Certain advantages of the main types of signal constellations for the transmission of high-volume information. The main requirements for manipulation codes were defined and a method for distinguishing signals from neighboring points of the constellation was defined. Considered of isometries of two-dimensional and three-dimensional manipulation codes. Codes of signals which have been chosen as pilot are given. A comparative analysis was carried out between signal constellations of quadrature amplitude-phase modulation (QAM) and cubic amplitude-phase modulation (CubeAM). It is offered the method to rise the efficiency using of sectional the hindrance codes in the feedback systems for the correction of error bursts.
