In this paper we propose a multicarrier code division multiple access (MC-CDMA) based architecture with variable spread- ing factor for the downlink of infrastructure wireless local area networks (WLANs). The objective of this proposal is to pro- vide service simultaneously and within the same radio chan- nel to several users even if their data rate requirements are dif- ferent. In addition, the bit error rate (BER) performance of our proposal is analyzed for four combining techniques and two network scenarios, one without multiple user interference (MUI) and one where the MUI reaches its maximum value. We consider a wide-band Rician fading channel with both indepen- dent and correlated frequency selectivity for the BER compu- tations. The main the purpose of the paper is to show how the MUI and the correlation among subchannels affect the BER performance of a downlink MC-CDMA system. |
