This program contains a Matlab link-level simulation environment for the ETSI standard DECT 2020 New Radio (NR+) (ETSI TS 103 636 v2). This software was initially developed by Maxim Penner and Roman Glazkov, this particular version is maintained by Alexander Pyattaev. Importantly, this is a hard fork, and was not intended to be compatible with upstream implementation.
The standard consists of multiple parts which can be found on the DECT Technical Committee (TC) webpage.
The complete physical layer of a DECT NR + transmitter is implemented. This includes all bandwidths, MIMO modes, channel coding etc. Additionally, BERs and PERs can be simulated in different wireless channel models, in particular doubly-selective channels. For the receiver, STO and CFO synchronization as well as most MIMO modes have been implemented.
- The simulation does not model the actual contents of PCC or PDC sections of the packet, and as such is not a protocol level simulator. You should not rely on this tool to model packet headers and other such MAC-related issues.
- implement basic MIMO algorithms for NSS > 1
- add phase error gradient correction due to SCO
- main_standalone.m: entry point to run simulations based off data in mat file with parameters. Useful for runs in SLURM etc.
- test_all.m: script to run
main_standalone.mwith reasonable parameters if you want to test things out.
The Matlab LTE Toolbox is required for channel coding and the Communications Toolbox for wireless channel simulation.
PERs of a SIMO (two receive antennas) system for different MCS over SNR in a Rician fading channel.
Resource mapping of STF, DRS, PCC and PDC in the time-frequency lattice.
