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

Adding the whole floder into the path

Getting Started

  1. Click here to download the raw data and put it into the data folder.

  2. You can quickly use TyrLoc by running WIFIAoA_Main/BLEAoA_Main/LoRaAoA_Main.
