Hello Experts.
For PTRS.
I came across following statement - “Due to the properties of phase noise, PTRS can have low density in the frequency domain but high density in the time domain.”
- My breakdown of this scenario - is linking phase noise to spectral regrowth - then to frequency domain graph (of phase noise- spectral regrowth - creating Inter carrier interference) and this ICI will cause ISI in time domain too, then why not PTRS have high dense in frequency domain ?
I am a bit confused while trying to understand why high density in the time domain ? Any basic clarification or Guidance will be helpful. Thanks
