Abstract

This paper presents a digital implementation of a Multi-Carrier Modulation scheme without spectral overlapping between sub-carriers. This scheme uses aQAM modulation and a square root Nyquist pulse shaping function. It guarantees orthogonality between sub-carrier signals even after transmission over a dispersive fading channel. The modulator and the demodulator use aK-pointDFT and a set of polyphase filters. Therefore all single-carrier equalization and detection techniques can be used in this Multi-Carrier Modulation system.
