'Port7-8'Single-antenna port, port 7, when NLayers = 1. Dual layer transmission, ports 7 and 8, when NLayers = 2.
'Port8'Single-antenna port, port 8
'Port7-14'Up to eight layer transmission, ports 7–14

UeOffset 0…319

UE-specific SRS offset

UePeriod 2, 5, 10, 20, 40, 80, 160, 320

UE-specific SRS periodicity, in milliseconds

VelocitylteHSTChannel

Train velocity, in kilometers per hour

WlteDMRS

NLayers-by-P precoding matrix for the wideband UE-specific beamforming of the DM-RS. P is the number of transmit antennas. An empty matrix, [], signifies no precoding.

ltePDSCH

Numeric matrix, [] (default)

NLayers-by-P precoding matrix for the wideband UE-specific beamforming of the PDSCH symbols. P is the number of transmit antennas. When W is not specified, no precoding is applied.

Window 'Left', 'Right', 'Centred', 'Centered'

If more than one subframe is input this parameter is required to indicate the position of the subframe from rxgrid and refgrid containing the desired channel estimate. Only channel estimates for this subframe will be returned. For the 'Centred' and 'Centered' settings, the window size must be odd.

WindowinglteOFDMModulate, lteOFDMInfo, lteRMCDL, lteTestModel

Number of time-domain samples over which windowing and overlapping of OFDM symbols is applied

lteRMCUL, lteSCFDMAModulate, lteSCFDMAInfo

The number of time-domain samples over which windowing and overlapping of SC-FDMA symbols is applied
