Iterative Broadband Source Localization
Coleman DeLude, Rakshith Sharma, Santhosh Karnik +3
In this paper we consider the problem of localizing a set of broadband sources from a finite window of measurements. In the case of narrowband sources this can be reduced to the pr…

Thomson's Multitaper Method Revisited
Santhosh Karnik, Justin Romberg, Mark A. Davenport
Thomson's multitaper method estimates the power spectrum of a signal from equally spaced samples by averaging tapered periodograms. Discrete prolate spheroidal sequences (D…

Improved bounds for the eigenvalues of prolate spheroidal wave functions and discrete prolate spheroidal sequences
Santhosh Karnik, Justin Romberg, Mark A. Davenport
The discrete prolate spheroidal sequences (DPSSs) are a set of orthonormal sequences in which are strictly bandlimited to a frequency band and maximal…
