Testbed of Intelligent SDR

The testbed consists of software and hardware parts. The software part includes LabVIEW 15.0 and MATLAB 13 running on WINDOWS 7 platform at transmitter and receiver end. The hardware consists of two NI PXIe-1085 chassis one at the receiver and one at the receiver.

Each hardware chassis is equipped with two vector signal generators (NI PXIe-5673) that acts as the transmitter and two vector signal analyzers that act as the receiver (NI PXIe-5663). Each VSG again consists of three parts: dual-channel arbitrary waveform generator (NI PXIe-5450), RF upconverter (NI PXIe-5611), and RF continuous waveform generator(NI PXIe-5652).

Each VSA also consists of three parts: RF down-converter (NI PXIe-5601), RF continuous waveform generator (NI PXIe-5652), and 16-bit analog-to-digital converter (NI PXIe-5622). The chassis is equipped with (NI PXIe-8135) embedded controller which has a 2.3 GHz Intel i7 microprocessor with all peripherals like USB, LAN, HDMI, etc.
