Description
  • V této práci byly popsány základní principy modulace OFDM. V simulačním prostředí Matlab Simulink byl namodelován OFDM multiplex. Pro zvýšení odolnosti proti vícecestnému šíření signálu byl použit adaptivní ekvalizér, fungující na principu násobení vstupní datové posloupnosti inversní hodnotou přenosové funkce kanálu. Byly analyzovány parametry přenosového systému OFDM v kanálu s šumem a vícecestným šířením. (cs)
  • A method of the orthogonal frequency division multiplex (OFDM) has a high spectral effectivity, low distortion and interference resistance. In this paper, the basic principles of the OFDM modulation are described. Simulation software the OFDM multiplex is designed in the Matlab Simulink. The OFDM model parameters are set according to the physical layer of the 802.11a wireless network. Simple adaptive equalizer is used for increasing of multipath resistance. Parameters of OFDM system are analyzed in channel with noise and multipath propagation.
