Abstract
The paper compares the performance of Kalman filter and hidden Markov model approaches for the recovery of speech from FM signals within impulsive noise environments. Two applications of speech recovery are investigated, namely within demodulation and post demodulation. Simulation studies are presented which illustrate the best case and worst case performance trends
