Abstract :
A novel and efficient algorithm for envelope detection based upon Hilbert transformation techniques is presented. The method relies exclusively on using differentiation to approximate the Hilbert transformation. The resulting detector is causal and does not require exact knowledge of carrier phase or frequency. The effectiveness of the method is illustrated through investigations of the estimation error performance in comparison with that of existing detectors. Simulation and experimental results demonstrate the superiority of the proposed method
