Performance comparison of multicarrier DS-SS radio access schemes for WLAN using measured channel delay profiles

In this paper we propose two different MCM (multicarrier modulation)-DS-SS radio access schemes for WLANs and we evaluate their performance in terms of bit error rate and frame error rate by using measured channel delay profiles, in different indoor environments. By comparing the obtained performance with the results of the DS-SS physical layer of the IEEE 802.11 standard, we point out some important architectural aspects and the potential limiting factors of the performance.
