NR Physical Resources Visualizer

Preface

A simple visualizer for NR(5G) resource grid visualization for L1(Physical Layer), based on 3GPP release-16.

Implemented via Python 3.8.8+(only tested on Win10/11).

Dependencies(managed by Miniconda):

• numpy
• matplotlib

Workflow

1. read *.json file as input, which describes the occurations of NR signals/channels,

   • Not completed yet

2. generate the signal/channel objects, which based on NrSignalCommon,

   • why not use duck-typing? To make sure derived class have method get_get_resource_grid_fragments()

3. use get_resource_grid_fragments to get fragments of resource grid, and fill them into class NrPhysicalResourceRenderer

   • max support 32 ports of L1

4. use NrPhysicalResourceRenderer.plot() to show the resource grids

   • you can specify which port to show

Finished

• CSI-RS downlink PHY initial supported

TODOs

• add support for more channels of NR
• finish the json support
• more annotations on the figures
• UT and more test cases
• automatic test on GitHub with travis CI
• published to pypi.org
• a simple UI to configure/switch figures
• performance optimization
  • multi-thread support
  • python JIT with numba
• documentations improvement
