An algorithm to estimate the Teager Energy (TE) based on Empirical Mode Decomposition (EMD) and Hilbert-Huang Transform (HHT) is proposed in this paper. The signal whose energy is to be estimated is decomposed into Intrinsic Mode Functions (IMFs) by EMD process and further analytical signal is reconstructed using Hilbert Transform (HT) to estimate(More)
— Cognitive radio is an emerging technology that aims for efficient spectrum usage. Cognitive radios have been proposed as a solution to the spectrum underutilization problem and have been proven to increase spectrum efficiency whilst providing opportunities for futuristic technologies. However, in this we are analyzing the performance of the cognitive(More)
Matched filter is often referred to as optimum filter. The most unique characteristic of the Matched Filter is that it produces the maximum achievable instantaneous SNR at its output when a signal plus additive white noise is present at the input. This paper presents a new algorithm for improving doppler profile detection of Radar echoes using Matched(More)
