PDSCH Extraction Equalization
PDSCH character extraction and alignment.
Description
The PDSCH Extraction Equalization block performs PDSCH character extraction and alignment.
The block performs the following actions:
-
Extracts PDSCH-related symbols of physical channel resources from the adopted ResGrid using indices.
-
Uses the estimated channel information ChEst and noise variance NoisEst to perform Minimum Mean Square Error (MMSE) alignment and returns the aligned PDSCH symbols as a complex matrix REs.
