This paper introduces a Gaussianity test for causal in-vertible time series. It is based on a quadratic form in dierences between sample means and expected values of certain nite memory nonlinear functions of the estimated innovation sequence. The test has, by construction, an interesting property: under reasonable assumptions on the regularity of the… (More)
A prototype of an enhanced QoS 802.11n circuit using a Tournament Contention Function (TCF) is presented in this article. First, the TCF developed is briefly explained. Then, a simple hardware implementation of this protocol in compliance with the 802.11n standard is proposed and evaluated.
