We investigate the use of adaptive bit loading in existing OFDM-based W-LAN standards.
The performance gain is assessed through simulation and the use of higher-rate codes is
considered to improve the performance. Some practical aspects, such as peak-to-average
power ratio, channel estimation, signalling and spectral flatness are also addressed.
