| Acronym: DiRecTRadio |
| Main Objective: In this project the main objective is to study, design, prototype and evaluate innovative System on Chip architectures and synthesizable models for flexible, all-digital and fully integrated transmitters for Cognitive Radio (CR) systems. Building all-digital flexible transmitters requires traversal competences on different areas, namely, reconfigurable digital systems, signal processing and RF design. These areas of expertise are covered by the members of the research team. Our approach to all-digital transmitter design will explore the huge computational power, input/output bandwidth and flexible integration capacity of modern FPGAs in order to build customizable computation and communication architectures as well as the required dynamic reconfiguration methodologies that fulfill the transmitters’ flexibility needs for future CR systems. This project will contribute to the state-of-art of all digital transmitters in several aspects, namely: - Advanced digital signal shaping techniques and corresponding implementation circuits that allow a fully FPGA-based flexible processing of high bandwidth signals. - Novel baseband to RF up-conversion techniques and corresponding fully integrated FPGA-based realization circuits that allow using flexible hardware modules for configurable and simultaneous multi-band and multi-standard operation. - Tight integration of signal shaping and up-conversion techniques with FPGA-based baseband processing engines for high throughput, low latency and fast reconfiguration times. |
