Fast frequency hopping OFDM concept

Abstract

A system concept, combining orthogonal frequency division multiplexing (OFDM) with fast frequency hopping (FFH), termed FFH/OFDM concept, is illustrated. Data symbols in the frequency domain are mapped to time domain samples by a unitary transformation based on a shuffled version of the well-known inverse discrete Fourier transform. The FFH/OFDM concept shows a promising performance.
