blockType: PDCCHExtractionEqualization

Path in the library:

/5G/PDCCH Extraction Equalization

Description

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

The block performs the following actions:

Retrieves elements of PDCCH-related physical channel resources from the received ResGrid grid usage of PDCCHInd 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 PDCCH symbols as a complex matrix.

Ports

Input

# ChEst — estimated information about the channel
the matrix

Details

Estimated information about the channel in the form of a complex matrix.
