A Fast Hadamard Transform for Signals with Sub-linear Sparsity in the Transform Domain
Robin Scheibler, Saeid Haghighatshoar, Martin Vetterli
A new iterative low complexity algorithm has been presented for computing the Walsh-Hadamard transform (WHT) of an dimensional signal with a -sparse WHT, where is a powe…
A new entropy power inequality for integer-valued random variables
Saeid Haghighatshoar, Emmanuel Abbe, Emre Telatar
The entropy power inequality (EPI) provides lower bounds on the differential entropy of the sum of two independent real-valued random variables in terms of the individual entropies…
Polarization of the Renyi Information Dimension with Applications to Compressed Sensing
Saeid Haghighatshoar, Emmanuel Abbe
In this paper, we show that the Hadamard matrix acts as an extractor over the reals of the Renyi information dimension (RID), in an analogous way to how it acts as an extractor of…
