GOALS
MATLAB Simulink Models on USRP
Distributed System
Use Raspberry/Banana Pi
Signal processing on Software
MOTIVATION
Signal Processing on software vs. hardware
Flexibility, scalability, portability
More applications of radios
MATLAB
Support packages for Raspberry Pi and USRP
Requires Windows Host
Generates Executables
Limitations
USRP requires gigabit ethernet
USRP blocks don’t work on Raspberry Pi
Support package required Raspberry Pi GPU
Host connected via:
WiFi
Switch
Ethernet Adapter
Banana Pi
Gigabit Ethernet
Similar Architecture
Cost effective
Different GPU
Banana Pi Substitute
Host connected via:
WiFi
Switch
Ethernet Adapter
MATLAB server has dependencies for GPU
*Raspberry Pi GPU
Host connected via:
WiFi
Switch
Ethernet Adapter
Deploy to Raspberry Pi
Transfer to Banana Pi
Simulink models work
USRP blocks do not
Solution
Custom blocks to replace USRP
S - Function
Data transmission and processing on Pi
