Abstract :
Multicarrier modulation techniques are finding growing interest for wireless local area networks (WLANs). Standards, such as Hiperlan type 2 and IEEE 802.11a, have adopted OFDM for transmission of high bit rates in these networks. In this paper we present a simple algorithm for multiuser bit loading in a multicarrier WLAN. The algorithm is based on carrier sense multiple access (CSMA) and it performs up to 50% better than conventional CSMA
