HERNANDEZ TORRES, Jorge Alejandro  e  TORRES GOMEZ, Jorge. BFSK waveform Demodulator based upon «Early-Late Gate Shynchronizer». EAC [online]. 2015, vol.36, n.3, pp. 13-20. ISSN 1815-5928.

This paper addresses a new algorithm for blind demodulation of BFSK signals by means of two techniques; the Early-Late Gate Synchronizer and the Quadratic Receiver. In order to implement the system, the cross-correlation factor between sections of the signal is obtained in order to estimate the transition between consecutives symbols. The performance of the proposed algorithm is described through several simulations with BFSK signals.
