In this work, we consider the amplify-and-forward (AF) two-way relay network where the two terminals T<inf>A</inf>, T<inf>B</inf> exchange their information through a relay node T<inf>R</inf> in a bi-directional manner and study the impact of the training-based channel estimation upon individual and sum-rate of the two users. We assume that in the(More)
We consider an energy constrained two-way wireless relay system, where a bidirectional connection between two terminals T<inf>A</inf> and T<inf>B</inf> is established via one decode-and-forward (DF) relay &#x211D;. We study the optimal power allocation that minimizes the total transmit power consumption, under given requirements on the end-to-end bit error(More)
For a three-node cooperative network model we propose a novel relaying strategy, referred to as selective Decode-and-Forward/Ampliy-and-Forward (selective DF/AF), and analyze its symbol error rate (SER) performance. In the proposed scheme, the relay always cooperate: when it is able to decode correctly the transmitted information symbols it forwards the(More)
We consider a dual-hop vehicle to vehicle (V2V) relay channel, where a source vehicle communicates with a destination vehicle using a third vehicle as a relay node. The inter-vehicle relay channel is the product of two independent fading processes generated by two independent groups of scatterers. A novel MMSE estimator is proposed for the aforementioned(More)
This paper focuses on an introduction to the test and measurement of different commercially available wireless standards. The different wireless working groups each present the unique specifications for the PHY in their standard documents. And while it may seem overwhelming to start working with new standards, the concepts for, and requirements of, physical(More)
