Software Defined Radio technologies for emergency and professional wide band communications

In this paper several RF architectures have been investigated in order to find a flexible, reconfigurable and multi-mode RF front-end for Software Defined Radio (SDR). The objective is to develop a new professional mobile broadband communication system, oriented to Public and Governmental Services. Different receiver prototypes based on the studied architectures have been implemented. The comparison of the RF architectures from the measurement results will be presented. The receiver prototypes have been validated for different types of modulation and data rates.
