Channel Protection: Random Coding Meets Sparse Channels
M. Salman Asif, William Mantzel, Justin Romberg
Multipath interference is an ubiquitous phenomenon in modern communication systems. The conventional way to compensate for this effect is to equalize the channel by estimating its…
Dynamic Updating for L1 Minimization
Muhammad Salman Asif, Justin Romberg
The theory of compressive sensing (CS) suggests that under certain conditions, a sparse signal can be recovered from a small number of linear incoherent measurements. An effective…
Beyond Nyquist: Efficient Sampling of Sparse Bandlimited Signals
Joel A. Tropp, Jason N. Laska, Marco F. Duarte +2
Wideband analog signals push contemporary analog-to-digital conversion systems to their performance limits. In many applications, however, sampling at the Nyquist rate is inefficie…
