MANY different techniques have been discussed in the literature to estimate the parameters of a chirp signal categorized as Transform, FilterBank, statistical etc. Majority of these methods have a trade-off between the accuracy and computational comp

In this manuscript, we propose a class of linear integral transforms that extends the capabilities of the Fractional Fourier Transform(FrFT), while preserving some key properties of the FrFT. The FrFT has diverse applications in literature, including

HF Communication has been synonymous with long ranges achievable using relatively inexpensive equipment. The downside though, has been the highly unreliable nature of the HF Ionospheric channel, which has deterred the development of systems capable o

The various techniques available for Chirp Parameter Estimation (CPE) can be categorized as Transform-based approaches, filter-bank approaches and statistical estimation based approaches. CPE involves estimation of time versus instantaneous frequency
