Wireless Testbench Applications on NI USRP Radios

Prebuilt Hardware Images

Wireless Testbench™ provides prebuilt hardware images that enable you to explore wireless applications for NI™ USRP™ radios by using MATLAB^® objects. This diagram is a high-level overview of how Wireless Testbench objects integrate SDR capabilities of supported radios.

Wireless Testbench software stack for objects

Using a Wireless Testbench object, you can configure the prebuilt hardware image to transmit, capture, or detect wireless signals and write your application code for experimenting and testing.

Wireless Testbench Object	Description
`basebandReceiver`	Configure NI USRP radio as baseband receiver
`basebandTransceiver`	Configure NI USRP radio as baseband transceiver
`basebandTransmitter`	Configure NI USRP radio as baseband transmitter
`preambleDetector`	Configure NI USRP radio as preamble detector
`energyDetector`	Configure NI USRP radio as energy detector

Standalone Peripheral Applications for Live Data I/O

Wireless Testbench enables the use of a supported NI USRP radio as a standalone peripheral for live data I/O using MATLAB System objects and Simulink^® blocks. This functionality utilises the default hardware image provided by the hardware vendor. This diagram is a high-level overview of how Wireless Testbench System objects and blocks integrate SDR capabilities of supported radios.

Wireless Testbench software stack for System objects and blocks

Using a Wireless Testbench System object™ or block, you can configure supported radios as a standalone peripheral to transmit and receive wireless signals and write your application code for experimenting and testing.

System Object	Simulink Block	Description
`comm.SDRuReceiver`	SDRu Receiver	Receive IQ data from the air for live processing with an NI USRP radio
`comm.SDRuTransmitter`	SDRu Transmitter	Transmit IQ data to the air with live processing with an NI USRP radio
