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 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
