The platform is currently under development in the Institute of Microelectronic and Wireless Systems (IMWS), Maynooth as part of the CTVR effort in cognitive radio systems. The platform operates in across the frequency band from 1.6GHz to 2.5GHz with the capability to support the GSM1800, DCS1800, PCS 1900, UMTS-FDD, UMTS-TDD and 802.11b standards. This demonstration will display the platforms capability to sense a particular channel, and identify the modulation scheme and communications standard in operation. It will also show the system's capability to move from one channel to another and implement arbitrary modulation schemes in these channels in both transmit and receive mode.

The system design using o the shelf components is detailed and early performance results are given. The demonstrator is focused on providing a suitable front end for a software implementation of the GSM1800, UMTS and IEEE802.11 standards. It performs the RF functions of the

The relevant system parameters such as SNR, IP3 and sensitivity are mined for the standard documents and these are placed in the context of requirements on the architectures and components required to implement the transceiver.
