Abstract :
In this paper, an application of a simplified second-order lattice-based adaptive IIR notch filter to binary FSK demodulation is presented. The design method and performance evaluation of the demodulator, based on mean-squared error analysis of the steady-state variable coefficient fluctuations of the adaptive notch filter are studied. Derived analytical results are compared with computer simulation results for confirmation
