Demodulation Reference Signals (DMRS) in 5G NR

Learn about demodulation reference signals or DMRS in 5G New Radio. This video discusses their use in joint precoding and channel estimation. You will also learn about the different settings available for DMRS, including time and frequency density and position within a slot.
This includes single-symbol vs. double-symbol, configuration type 1 and 2, mapping type A and B, and additional positions. You will learn how those settings support both single user and MU-MIMO. Finally, this video demonstrates most of those settings with an interactive application written with 5G Toolbox™.

Nice video, small enough topic, easy to follow.
Are those two subcarrier options really the only two patterns in which DMRS can be utilized?

[@rashpinderarora34]

great explanation!! Where i can find the "5G NR downlink signal generator" used in this video ?

Hi, thanks for such great material.
I have question. in PDSCH DM-RS single Vs. double is it possible to have double symbol DM-RS with type A position 3 which cause to have 2 PDSCH DM-RS in Symbols #3&4?

[@r.vigyanarthi1670]

I need help in dvb
