Software Configurable Receivers
Software Configurable Receivers J.-F.Luy, IEEE Fellow DaimlerChrysler Research, Ulm Germany e-mail: johann-friedrich.luy@daimlerchrysler.com Heterodyne and Direct Conversion Homodyne receivers have been studied for a long time. It can be shown that the classical advantages as high sensitivity and high selectivity can not be transferred easiliy to the requirements arising from software configurabl
High-Level Design using Coupled Electromagnetic, Circuit and System Simulation
High-Level Design using Coupled Electromagnetic, Circuit and System Simulation Zoltan Cendes Ansoft Corporation Pittsburgh, PA 15219 zol@ansoft.com A procedure for coupling electromagnetic field simulation together with circuit and system simulation is presented. The procedure employs automatic adaptive mesh generation to make the electromagnetic analysis transparent to the user. It uses model ord

Importance of synchronization in wireless communication. Abstract Marco Siccardi DATUM International Sales Background: Wireless networks come in many different architecture, from the familiar cellular phone network to fixed broadband to wireless LANs. Although each is a very different application they are all dependent on a common base station architecture. At one end of the wireless network, the
