My industrial experience has been mainly in the area of software and specifically for signal processing in communication systems.  I have developed real-time receivers for telephone line modems, I have been part of a team that developed a "world first" real-time Satellite-UMTS demonstrator system, and I lead the physical layer development of a 3GPP compliant multiuser detection simulator.

For the Satellite-UMTS system I was responsible for the transmitter/receiver architecture, the implementation and testing of the receiver algorithms.  I lead a small team in the validation of these algorithms in VHDL and the subsequent integration and testing on a real-time hardware platform.  The receiver acquisition and tracking algorithms were challenging due to the large frequency offset present in a LEO Satellite channel.  Under this project I lodged one patent on acquisition techniques with large frequency offset.
 

The 3GPP compliant multiuser detection simulator goals were to validate interference cancellation algorithms with antenna arrays in a standard compliant framework, to develop solutions to outstanding research problems, and to determine the system level benefits of the algorithms including cell size and cell capacity improvements.  I was the workpackage leader for the physical layer implementation, and I worked together with other European universities and companies.  The research project was sponsored by the European Commission and was titled ASILUM (www.ist-asilum.org).  Under this project we determined the excellent performance of the receiver under different conditions.  In the process of the work I lodged two patents on acquisition techniques for such receivers.  We were also able to determine the overall system benefits of the receiver in terms of cell size and cell capacity; an important measure to justify the commercialisation of the technique.
