Implementation and performance of a multi-band transceiver for software defined radio

There are various mobile communication standards in use worldwide. Software defined radio (SDR), which enables the creation of multi-standard terminals, is one of the best ways to achieve seamless mobile communications. To realize an SDR mobile terminal, it is necessary to minimize terminal size and power consumption. NTT developed an RF chipset for a multi-band transceiver and a signal processing board using a reconfigurable processor. This paper describes its implementation and the performance of the multi-band RF chipset along with the results of an evaluation of the signal processing unit.
