Abstract

In this paper, we introduce a modified version of the IEEE 802.11a protocol and evaluate its performance. The new protocol is a combination of the standard Medium Access Control (MAC) protocol of 802.11 and the Multi-Carrier Code Division Multiple Access (MC-CDMA) scheme, a novel, high capacity multicarrier modulation technique. The system can achieve higher throughput and shorter delays, owing to the division of the spectrum in a number of parallel codechannels.
