Comparing Measures of Sparsity
Niall P. Hurley, Scott T. Rickard
Sparsity of representations of signals has been shown to be a key concept of fundamental importance in fields such as blind source separation, compression, sampling and signal anal…
Parity properties of Costas arrays defined via finite fields
Konstantinos Drakakis, Rod Gow, Scott rickard
A Costas array of order is an arrangement of dots and blanks into rows and columns, with exactly one dot in each row and each column, the arrangement satisfying certain…
On the generalization of the Costas property in the continuum
Konstantinos Drakakis, Scott Rickard
We extend the definition of the Costas property to functions in the continuum, namely on intervals of the reals or the rationals, and argue that such functions can be used in the s…
Canonical time-frequency, time-scale, and frequency-scale representations of time-varying channels
Scott T. Rickard, Radu V. Balan, H. Vincent Poor +1
Mobile communication channels are often modeled as linear time-varying filters or, equivalently, as time-frequency integral operators with finite support in time and frequency. Suc…
