WHT/OFDM - An Improved OFDM Transmission Method for Selective Fading Channels

White Paper However, the OFDM modulation also exhibits drawbacks such as: low immunity against frequency selective fading and a high peak-to average power ratio (PAPR), which necessitates the usage of a highly linear amplifier. [21 Oct 2004]
