Representation of Composite Fading and Shadowing Distributions by Using Mixtures of Gamma Distributions
Abstract—The Nakagami-lognormal distribution is the commonly used composite distribution for modeling multipath fading and shadowing. In this paper1 , simple and new form of dist...

An Efficient Algorithm for the Approximate Median Selection Problem
We present an efficient algorithm for the approximate median selection problem. The algorithm works in-place; it is fast and easy to implement. For a large array it returns, with ...
