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 configuration of the hardware structure, to achieve new functionality. Now the strong launch of this new structure a powerful platform for software radio innovation, a wealth of resources can be used to study innovation and application development.

I、The RF module:
     Integrated radio frequency subsystem experimental system using the popular direct-conversion technology, the formation of zero, the low frequency communication system. Zero-IF and low IF communication system is now mainstream digital radio communications and mobile communications architecture. With adjustable transmission power, you can adjust gain acceptance to facilitate the formation of AGC loop. 50M ultra-wide bandwidth, can support WLAN, high-speed communication protocol of the experiment and development.

II、The filter module:
     Different communication systems need to use a different filter modules, the system provides support for different filter modules.

III、DSP modules:
     The system supports a different DSP.

IV、AD / DA modules:
     High-speed dual-channel AD / DA system, complete analog and digital domain domain signal conversion.

V、FPGA modules:
     System supports different models and capacity FPGA, for a variety of different applications.

VI、ARM modules:
     As a senior communications systems, high-performance multi-functional host processor is indispensable.

VII、Digital communication signal generator and software:
     Radio integrated with a powerful experimental system, the communication signal generator. Signal generator can produce from a digital radio communication channel and the impact on the system can be affected differently baseband signal. Comprehensive experimental system with the common use of radio, will produce a signal sent to the receiver, to verify the performance of the receiver.

     The software part includes control software and signal processing software. Control software can complete the wisdom of the radio parameters, adaptive configuration, so that radio can automatically adapt to their environment, and provide an experimental user to select, design and implementation of different wireless communication signal modulation and signal interference and to consider impact of various factors, such as: fading channels, multipath channel, phase noise, carrier frequency offset, etc., to provide users with easy to understand and operate interface and tools. Signal processing software includes a variety of modulation signal corresponding to a whole generation under the program (including coding, modulation, etc.) and receive the program (including time and frequency synchronization, decoding, demodulation, etc.)
