A modular testbed for hardware reconfigurable radio at the 2.4 GHz ISM band
0 ()
Optional Fields
A modular testbed for use in developing software defined radio is documented in this paper. The testbed is focused on the 2.4 GHz ISM band but may be used at other frequencies. An RF transceiver with variable transmit/receive frequencies and bandwidths is provided. It provides the capability to support many modulation schemes and standards such as GSM, UMTS, IEEE 802.11b and parts of the IEEE802.16 standards. It performs the RF functions of the radio, with the other PHY and MAC layer functions such as equalisation and error-coding being performed by a host computer. It communicates with the host computer system through a USB2 interface allowing data rates of up-to 60Mbytes a second. An API is used for communication with the host computer system allowing for modulation/demodulation and coding/decoding in software on the host system and reconfiguration of the radio system.
