Abstract :
IEEE 802.11a/e has become a worldwide wireless local area network (W-LAN) standard, with a rapid development. Many proposals have been made for its further expansion, and some of them focus on multicarrier code division multiple access (MC-CDMA), a novel, high capacity, multicarrier modulation scheme. In this paper we present an analysis of the error models for radio transmissions in such systems. An accurate model of the channel is necessary for the performance evaluation of the protocol by means of computer simulations. Focusing on the estimation of the signal to interference and noise ratio (SINR) at the detector and on the calculation of a packet error ratio (PER), in this contribution we discuss a modeling approach which allows an efficient calculation of frame transmissions over a MC-CDMA shared radio channel.
