Folded orthogonal frequency division multiplexing
We propose and demonstrate a new sub-carrier multiplexing scheme, utilizing orthogonal, periodic-sinc-shaped sub-carrier spectra. This 'folded' OFDM allows for multi-carrier bands to be generated with the precise, rectangular frequency definition of Nyquist WDM.

Interleaved orthogonal frequency division multiplexing system [PDF]
A new orthogonal frequency division multiplexing (OFDM) system for wireless communications over frequency selective fading channels is presented. The proposed interleaved orthogonal frequency division multiplexing (IOFDM) system promises higher code rate as compared to the conventional OFDM system without bandwidth expansion and with very slight ...
