5G NR Channel Estimation by Slot instead DM-RS

11 views (last 30 days)
Hello, I wanted to use the nrchannelestimate from Matlab to perform Channel Estimation, but not only via DMRS Signals as references.
I wanted to give every Symbol as a Pilot. My question would be the following: Do I need to change the code from nrchannelestimate.m somewhere, or is it sufficient if I just give all symbol values and indices as arguments instead of the DMRS symbols and indices ?
I am aware that there is nrperfectchannelestimate, but I assume that the receiver does not have perfect synchronization etc, that's why I want to use nrchannelestimate

Hi Fatih,
You can use nrChannelEstimate directly and provide all the symbol values and indices as arguments.

In general, any standard specifications (like 5G, LTE, WLAN) doesn't indicate about the receiver. It only indicates about the tranmissions. Some aspects of estimations will be provided in the measurements section, as part of any specified measurement process. The channel estimation is similar to any OFDM system having pilot symbols. You can look over this paper to understand better about channel estimation "On Channel Estimation in OFDM Systems". There are even other different papers in the literature about this topic.
