Zero Crossing Based Spectral Analysis
… of the timed zeros, both real and complex, of a band-limited signal. Mathematics essential to the study is explained and the method of using a simple invertible transform to convert complex zeros to real zeros, otherwise known as zero crossings, is considered. The work of key researchers in the …

Reconstruction from non-uniform samples
Exact reconstruction of a band-limited signal from its non-uniform samples involves the use of Lagrange interpolation, which is impractical to implement as it is computationally difficult. This thesis develops approximate reconstruction methods based on time-warping to obtain reconstruction of …

A hardware platform to test analog-to-information conversion and non-uniform sampling
… tells us that in order to fully recover a band-limited signal previously converted to discrete data points, said signal must have been sampled at a frequency greater than twice its bandwidth. This theorem puts a burden on circuits like ADCs, in the sense that the higher the bandwidth of a …

Compressive Detection and Estimation with Applications to Cognitive Radio and Radar
According to Nyquist Sampling theorem, a band-limited signal can be reconstructed accurately if the sampling rate exceeds twice the maximum frequency of the signal. In many scenarios, this Nyquist sampling rate cannot be achieved due to hardware limitations. Compressive sensing (CS) is a technique …
