Abstract

In this paper, we propose a novel FSK scheme that enhances performance and throughput relative to traditional FSK. Specifically we propose a novel BFSK implementation where, rather than frequency f₀ representing bit '0' and f₁ representing bit '1', we transmit multiple, orthogonal, in-phase carriers around f₀ or f₁ to represent binary information. We demonstrate the high performance of this FSK system in frequency selective channels, where a simple coherent reception technique enables diversity gain (resulting in significant performance improvement relative to traditional BFSK). We also introduce the concept of dense pulse packaging (DPP) that ensures a doubling of the data rate with minimal cost in performance, by pseudo-orthogonal positioning of pulse shapes at the transmitter.
