Software Defined Radio (SDR) is a communications and electronics technology, the most important and one of the most active areas of research. Software radio to a common, standard, modular hardware platform as the basis, through software programming to implement the various functions of the wireless transceiver, from a hardware-based, for the purposes of the transceiver design freed. Software radio architecture emphasizes the openness and full programmability through software updates to change the settings of hardware structure, to achieve new functionality. The equipment is a powerful novel structure of the software radio platform for innovation, rich resources can be used to study innovation and application development.
System resources:
1. The system of each node can be portable hand-held, a real mobile communication, facilitate innovation and
experiment.
2. Fully support true wireless communications, mobile, can network (point to point network, star network, mesh
network.)
3. Support the wireless data communications test, data for wireless transmission of voice, video information.
4. Optional support bands, each band multi-channel support. Band Support 700M ~ 1.2G, CNC adjustable.
5. RF part directly in the portable circuit board, without external modulation, demodulation box, to achieve true
portability.
6.RF AD / DA FPGA MCU architecture, each module can operate independently, can be upgraded.
7. The rich resources of hardware interface, can be 2 development.
8. With a 1800mAH battery and charge and discharge management circuitry.
9. All plexiglass shell, compact structure.
10. With a complete multi-node network communications example.
11. To wireless sensor network (802.15.4), WLAN, mobile multimedia broadcasting system, the latest wireless
communication protocol;
12. System requirements can be developed strong research and could not have been commercially used single-
chip transceiver and the wireless module to complete, the signal received by the RF part of the complete,
digitized by the AD part of the completion of demodulation to within the FPGA, protocol processing in
the CPU module to complete, real-time requirements can be observed through the oscilloscope and sent
to the receiver analog baseband signal waveform can be observed in various parts of the signal RF conditions.
