MIMO Gaussian channels with arbitrary inputs: optimal precoding and power allocation
We investigate the linear precoding and power allocation policies that maximize the mutual information for general multiple-input multiple-output (MIMO) Gaussian channels with arb...

A New Deterministic Parallel Sorting Algorithm with an Experimental Evaluation
We introduce a new deterministic parallel sorting algorithm based on the regular sampling approach. The algorithm uses only two rounds of regular all-to-all personalized communica...

Signaling Over Arbitrarily Permuted Parallel Channels
The problem of transmission of information over arbitrarily permuted parallel channels is studied here. The transmitter does not know over which channel a certain codesequence will...

Capacity of the Discrete-Time AWGN Channel Under Output Quantization
We investigate the limits of communication over the discrete-time Additive White Gaussian Noise (AWGN) channel, when the channel output is quantized using a small number of bits. W...

Simultaneous broadcast revisited
Simultaneous Broadcast protocols allow different parties to broadcast values in parallel while guaranteeing mutual independence of the broadcast values. In this work, we study va...

Statistical Threshold Design for the Two-State Signal-Dependent Rank Order Mean Filter
The signal-dependent rank order mean (SD-ROM) ?lter is effective at removing high levels of impulse noise from 2D scalar-valued signals. Excellent results have been presented for ...

On the Blind Classification of Time Series
We propose a cord distance in the space of dynamical models that takes into account their dynamics, including transients, output maps and input distributions. In data analysis app...
