This document describes the physical simulators, also called "unitary simulators", or short "physims".
[[TOC]]
Introduction
There are several unitary simulations for the physical layer, testing individual L1 transport/control channels using Monte-Carlo simulations, for instance:
nr_pucchsimfor 5G PUCCH,nr_dlsimfor 5G DLSCH/PDSCH,nr_prachsimfor 5G PRACH,dlsimfor 4G DLSCH/PDSCH, etc.
These simulators constitute the starting point for testing any new code in the
PHY layer, and are required tests to be performed before committing any new
code to the repository, in the sense that all of these should compile and
execute correctly. They provide estimates of the transport block error rates
and HARQ thoughput, DCI error rates, etc. The simulators reside in
openair1/SIMULATION/LTE_PHY and openair1/SIMULATION/NR_PHY. For instance,
nr_dlsim is built from openair1/SIMULATION/NR_PHY/dlsim.c.
Further unitary simulation of the coding subsystem components also exists in
openair1/PHY/CODING/TESTBENCH, e.g., ldpctest for encoding/decoding of
LDPC.
These are the simulators known to work properly and tested in CI:
- 4G:
dlsim,ulsim - 5G:
nr_dlsim,nr_ulsim,nr_dlschsim,nr_ulschsim,ldpctest,nr_pbchsim,nr_prachsim,nr_pucchsim,polartest,smallblocktest,nr_psbchsim(sidelink)
These tests are run in this pipeline: RAN-PhySim-Cluster.
