LimeSDR-Matlab-NR-CellSearch

General

This repository contains a wrapper for LimeSDR-USB drivers that allows to work from Matlab. All necessary files for the wrapper is located in the folder "_library". You can find basic examples for the usage of the library with Matlab 5G toolbox.

Prerequisites

1. Matlab
2. LimeSDR-USB

Usage

1. Add the folder "_library" in your matlab example folder suach as NRCellSearchMIBAndSIB1RecoveryExample
2. Add the code of lms_addin.m in NRCellSearchMIBAndSIB1RecoveryExample.m after the end of loadFromFile
3. Connect LimeSDR-USB
4. Run the examples

System configuration

Original system configuration:

1. Windows 10
2. Matlab with 5G Toolbox
3. LimeSDR-USB

Known issues

1. First sample block always droped some packets.
2. If you get LimeSDR error: Rx calibration: MCU error 5 (Loopback signal weak: not connected/insufficient gain?), Increasese the gain(0-60).
3. Some USB3.0 TypeC HUB droped packets every 4 sample block in 30.72MSPS made it hard to decode sib1. In my test Ugreen HUB is OK.
