PDSCH Demodulate

Decoding the physical downlink of the PDSCH.

blockType: PDSCHDemodulate

Path in the library:

/5G/PDSCH Demodulate

Description

Block PDSCH Demodulate allows you to get a sequence of bits obtained as a result of performing reverse processing of the PDSCH. The standard [1] sections 7.3.1.1 -7.3.1.3 for this carrier configuration and the configuration of the common downlink channel PDSCH and noise dispersion information are used for decoding.

Ports

Entrance

DCIBits — input message DCI
matrix

A sequence of DCI bits.

Data type: Int64

REs — aligned characters PDSCH
matrix

Aligned PDSCH symbols in the form of a complex matrix.

Data type: ComplexF64

NoiEst — estimated information about noise dispersion
positive scalar

Estimated information about noise dispersion.

Data type: Float64

SSBInd — MIB information and parameters for the pass block:q[<br>] vector

MIB information and parameters for the block (NID structure and ncelid cell identifier) in the form of a vector with integer values.

Data type: Int64

Output

PDSCHBits — a sequence of bits for encoding the PDSCH pass block:q[<br>] vector

A sequence of bits for encoding the PDSCH block as a vector.

Data type: Float64

Parameters

The main

Block Pattern — ID of the pass frequency range:q[<br>] Case A | Case B (By default) | Case C | Case D | Case E

For the 5G standard, the frequency range used is specified in the documentation.

Designation of the frequency range Frequency range
