Optimal transmission strategies for rayleigh fading relay channels
In this paper, a decode-and-forward (DF) single relay model in a Rayleigh fading environment is considered. The outage probability and ergodic rate for this model are derived. With...

A Symbolic Approach to Bernstein Expansion for Program Analysis and Optimization
Abstract. Several mathematical frameworks for static analysis of programs have been developed in the past decades. Although these tools are quite useful, they have still many limit...

The Bayesian Learner is Optimal for Noisy Binary Search (and Pretty Good for Quantum as Well)
We use a Bayesian approach to optimally solve problems in noisy binary search. We deal with two variants: • Each comparison is erroneous with independent probability 1 − p. ...

Optimal Multiple Description Transform Coding of Gaussian Vectors
Multiple description coding (MDC) is source coding for multiple channels such that a decoder which receives an arbitrary subset of the channels may produce a useful reconstruction...
