Reconfigurable Radio Testbed

In this paper a model of a reconfigurable radio testbed is presented. The hardware requirements utilized for a software defined transceiver which covers a wide band of communication standards such as: 2G/3G mobile, IEEE 802.11x, IEE 02.16x and IEE 802.20x are detailed. Specific details for the analog digital conversion are given. The system uses a direct conversion architecture for both up-conversion and down-conversion. Receiver and transmitter features are detailed, and early performance results are shown in this paper
