| contents | Low complexity demodulator for BFSK waveforms based on polygonal approximation Jorge Torres-Gómez Fidel Ernesto Hernández-Montero Joachim Habermann Ingeniería BFSK digital demodulation polygonal approximation The present article relates in general to digital demodulation of Binary Frequency Shift Keying (BFSK waveform). The objective of the present research is to obtain a new processing method for demodulating BFSK-signals in order to reduce hardware complexity in comparison with other reported. The solution proposed here makes use of the theories of matched filters and curve segmentation. The article describes the integration and configuration of a Sampler Correlator and polygonal segmentation blocks in order to obtain a digital receiver for properly demodulating the signal received. The proposed solution is shown to reduce dramatically the complexity in hardware and has a better performance regarding noise in comparison with other reported. Theoretical details concerning limits of applicability are also given by closed-form expressions. Simulation experiments are illustrated to validate the overall performance. 2015 artículo científico 0120-6230 https://www.redalyc.org/articulo.oa?id=43038629005 en http://www.redalyc.org/revista.oa?id=430 Revista Facultad de Ingeniería Universidad de Antioquia application/pdf Universidad de Antioquia Revista Facultad de Ingeniería Universidad de Antioquia (Colombia) Num.74 |
