Performance study on frequency-domain link adaptation in IEEE 802.11a wireless LAN

The link adaptation scheme in the current IEEE 802.11a technical specifications only consider channel variation in the time-domain, and assume all the data subcarriers use the same modulation mode and coding rate once the transmission data rate is determined. However, in the frequency-selective fadi...
