Any examples of finding the start of a frame for an asynchronously captured NR-TM?

The example provided uses a trigger only to analyze the TM or is processed as a file at the start of an already synchronized frame.

I want to analyze the TM signal from a capture file whose frame start is unknown.

• EVMMeasurementOfNRDownlinkWaveformsExample

Any examples?

NR-TM has no SSB.

Hi Jongmin,

For analyzing a TM signal from a capture file with an unknown frame start, there are no exact documentation or examples present as of now.

From the following example '5G NR Waveform Acquisition and Analysis' it is showed how to generate a 5G NR test model (NR-TM) waveform

• https://www.mathworks.com/help/instrument/5g-nr-waveform-acquisition-and-analysis.html

However, this example assumes that the frame start is known. For an unknown frame start, you might need to implement a custom synchronization algorithm to detect the start of the frame. This could involve correlating the received signal with a known preamble or pilot sequence, or using statistical methods to detect the start of the frame.

I hope this helps!
