1. Generalized Bandpass Sampling Receivers for Software Defined Radio
Abstract : Based on different sampling theorem, for example classic Shannon’s sampling theorem and Papoulis’ generalized sampling theorem, signals are processed by the sampling devices without loss of information. As an interface between radio receiver front-ends and digital signal processing blocks, sampling devices play a dominant role in digital radio communications. READ MORE

2. Dielectrically Loaded Quad-ridge Flared Horns for Ultra Wideband Reflector Feed Applications in Radio Astronomy
Abstract : Reflector-based radio telescopes are used as tools for observations in both radio astronomy and space geodesy. To observe the weak sources in space, highly sensitive receivers, fronted by optimized reflector feeds, are therefore needed. READ MORE

4. Flexible wireless receivers : on-chip testing techniques and design for test
Abstract : In recent years the interest in the design of low cost multistandard mobile devices has gone from technical aspiration to commercial essential. Usually, the emerging wireless applications prompt the conception of new wireless standards. The end user wants to access voice, data, and streaming media from single wireless terminal. READ MORE

5. Reconfigurable Impedance Matching Networks for Radio Receivers
Abstract : Mobile phones become smaller but include more advanced functions for every new generation. This paradox is possible since reduced transistor size and increased integration of digital building blocks free space for new functions. READ MORE
