PDSCH Extraction Equalization

Extraction and alignment of PDSCH characters.

blockType: PDSCHExtractionEqualization

Path in the library:

/5G/PDSCH Extraction Equalization

Description

Block PDSCH Extraction Equalization performs extraction and alignment of PDSCH characters.

The block performs the following actions:

  • Retrieves symbols of PDSCH-related physical channel resources from the received ResGrid grid usage of indexes.

  • Uses the estimated information about the channel ChEst and the noise variance NoisEst to perform Minimum Mean Square Error alignment (MMSE) and returns the aligned PDSCH symbols as a complex matrix REs.
