Abstract :
In this paper, we investigate the performance of two popular multicarrier transmission schemes, OFDMA, and MC-DS-CDMA, on severely fading channels. Channel models are drawn from our experimental work measuring the wireless channel in the 5 GHz band, around airport surface areas. Results indicate that multicarrier schemes can outperform their single-carrier counterparts, particularly when configured to account for the channel characteristics
