Abstract

This paper evaluates the performance of an MC-MFSK (multicarrier multilevel frequency shift keying) based system in the presence of Rayleigh fading. MC-MFSK is a new spread spectrum multiple access technology with the desirable properties of frequency diversity, near-far resistance, and multipath resolvability. The MC-MFSK scheme transmits a symbol in parallel over multiple sub-channels using OFDM (orthogonal frequency division multiplexing). We assume that each sub-channel has an independent flat fading process. Since the MC-MFSK receiver employs threshold detection, the selection of a suitable threshold is also discussed. Finally, comparisons with other MFSK-based spread spectrum systems are made to demonstrate the higher capacity of this new scheme
