The library of reference models of the physical layer signals

Abstract

The wireless communication is very widely used information transmission systems. Wireless networks differ from cable networks on physical and partially on data link layer OSI in use of different methods of modulation. The library of reference models of signals of the physical layer intended for creation of mathematical models of telecommunication protocols in wireless systems is provided. Creation of such models is caused by need of a research of methods of digital signal processing. The principal feature of these models consists in use of an algebraic method of processing of difficult signal constructions which allows to avoid use of a method of fast Fourier transform. The library contains the generalized models of signals m-PSK with absolute and relative phase-shift keying and the signal OFDM model. The possibility of representation of a signal in the form of the discrete samples, and also record and reading from the file is realized.
