an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

An Overview on Multiple Antenna Relay Selection in Multiuser network MIMO system

The use of multi-antenna relays has emerged as a very promising technique for combating fading, enhancing throughput and extending coverage in emerging w ireless broadband netw orks.In practical mult i-user multi-relay systems, not all nodes are able (or allow ed) to cooperate during data transmission. Selecting subsets of advantageous relays and users simultaneously for cooperation and communi...

Network Coding-Based Retransmission for Relay Aided Multisource Multicast Networks

This paper considers the reliable transmission for wireless multicast networks where multiple sources want to distribute information to a set of destinations with assistance of a relay. Basically, the reliability of a communication link is assured via automatic repeat request (ARQ) protocols. In the context of multisource multicast networks, the challenge is how to retransmit the lost or errone...

Performance Evaluation of Fixed and Mobile Relay in WiMAX System

AbstrAct: Future wireless communication systems are expected to provide more stable and higher data rate transmissions in the whole network. WiMAX is one of the technologies to cover diverse geographic regions. WiMAX covers the high dense urban areas and provide access over large geographic regions in remote rural area. However, in both scenarios it is challenging to cover the entire service ar...
