TyrLoc

TyrLoc is a Low-cost Multi-technology MIMO Localization System with A Single RF Chain.

• Low-cost: Cheap SDR and inexpensive antenna array extension
• Multi-technology: Compatible with various protocols
• Single RF chain: A novel method to calibrate the phase distortion caused by CFO

Requirements

MATLAB R2020a

Add-Ons in MATLAB:
Signal Processing Toolbox
WLAN Toolbox
Communications Toolbox Library for the Bluetooth Protocol
Communications Toolbox Support Package for Analog Devices ADALM-Pluto Radio
