This paper introduces a new spread-spectrum multiple access scheme based on multicarrier multilevel frequency shift keying (MC-MFSK). This new approach shares some of the advantages of both frequency-hopping (FH) and direct-sequence (DS) spread-spectrum systems, while overcoming some of their disadvantages. The MC-MFSK scheme transmits a symbol in parallel over multiple sub-channels using OFDM (orthogonal frequency division multiplexing). MC-MFSK has the desirable properties of frequency diversity, near-far resistance, and multipath resolvability. Arguably, this not only make MC-MFSK a simple yet competitive spread-spectrum technology but also make it a strong candidate for future high-speed wireless systems.
