Abstract of Lecture

Performance and efficiency will be key design requirements for future communications transceivers.  Systems must also be adaptable in order to minimize power and maximize throughput as environmental conditions and user requirements change. This lecture will present architectures and design techniques to achieve these goals for Ultra Wideband (UWB), multiple antenna (MIMO) and Cognitive Radio systems. This lecture will give the following details

l         Introduction to standard OFDM Ultra Wideband (UWB) and Pulsed-OFDM UWB

n       Standard OFDM with large FFTs

n      Architectures to implementation of Pulsed-OFDM UWB with less hardware and power

n      A hardware model of the UWB channel

l         MIMO system

n      A promising approach based on Geometric Mean Decomposition (GMD)

n      Throughput and design complexity results for a range of MIMO systems

l         Cognitive Radio systems

n      Flexible platform in which aspects of the system can be reconfigured dynamically

n      Programmable functional units and network-on-chip architectures
