PEDRAZA, Luis; HERNANDEZ, Cesar  and  BALLESTEROS, Dora María. Model of frequency selective fading. Rev.fac.ing.univ. Antioquia [online]. 2011, n.58, pp. 114-122. ISSN 0120-6230.

In this paper a mathematical analysis of the frequency selective fading produced by multipath propagation is presented, as well as recent techniques to reduce the effects of this phenomenon as: the diversity of antennas, the Rake receiver, the adaptive equalization and OFDM (Orthogonal frequency division multiplexing).

Keywords : Fading; orthogonal frequency division multiplexing; diversity; equalization; cognitive radio.
