Abstract
We propose a novel preamble sequence generation approach for continuous phase modulation based on prolate spheroidal wave functions (CPM-PSWF) for very low-frequency (VLF) system that can be generated on the carrier without post-modulation. The original principle, inspired from the PSWF frequency shaping pulses, is presented. From the autocorrelation of the proposed preamble and correlation performance with the other received signals in VLF system, the excellent detection characteristic of the proposed preamble is verified, under both Gaussian and non-Gaussian noise. The correct detection probability of the proposed preamble is more than 84% under Gaussian noise when Eb/$N_{{0}} \ge 0$ dB.
期刊介绍:
The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
