Goal: design and test a new suite of digital
communication labs based on the concept of SDR.
• Signal processing and systems. Some
experience with communication systems and
digital signal processing
• ECE301, ECE302 is preferred for this project.
• Good knowledge of MATLAB.
• Software-defined radio (SDR) is a radio communication
system where components that have been typically
implemented in hardware are instead implemented by means
of software on a personal computer or embedded system.
• SDR functions by sampling an incoming signal (A/D),
performing user-specified functionality on said signal, and
then reconstructing the (D/A), processed signal into a viable
output signal.
•The Universal Software
Radio Peripheral (USRP) is
the hardware platform being
used to test and implement
Simulink radio.
Using SDR for communication labs have many advantages
• Easy to Build (Less wire connections)
• Intuitively Design (Simulink is a graphical interface, just
drag and drop components and connect them)
• Cost Effective (Fewer needs for expensive equipment)
Communication system lab set up

• Gigabit Ethernet Streaming allows up to 100 MS/s
sample rate.
• Fully-Coherent MIMO Capability.
• SBX daughterboard provides 40 MHz bandwidth
capacity.

• Simulink is a data graphical programming language
tool for modeling , simulating and analyzing
multidomain dynamic systems.
• Simulink provides a graphical editor, customizable
block libraries, and solvers for modeling and
simulating dynamic systems. It is integrated with
MATLAB® , enabling you to incorporate MATLAB
algorithms into models and export simulation results to
MATLAB for further analysis.
• Amplitude modulator built with Simulink blocks
(functions generator, multiplier, oscilloscope, spectrum
analyzer)
