Logical root sequence index (RACH_ROOT_SEQUENCE)

`Shortened`

0 (default), 1

Option to shorten the subframe by omitting the last symbol, specified as 0 or 1. If `1`, the last symbol of the subframe is not used. For subframes with possible SRS transmission, set `Shortened` to 1 to maintain a standard compliant configuration.

`SRS` `'on'`

Enable SRS related configuration parameters (set SRS to `'on'`) for RMCs which optionally support SRS, or a complete or part SRS structure. If absent, no SRS configuration is created.

`SSC`

0 (default), 1, 2, 3, 4, 5, 6, 7, 8, 9

Special subframe configuration (SSC)

`SSS` `'Off'`, `'On'`

Secondary synchronization signal (SSS) correlation mode

`SSSPower`

Secondary synchronization signal (SSS) symbol power adjustment, in dB

`SubcarrierSpacing`

Subcarrier spacing of PRACH preamble, in Hz (deltaf_RA)

`SubframeConfig` 0…15

Sounding reference signal (SRS) subframe configuration

`SubframeType` `'Downlink'`, `'Uplink'`, `'Special'`

Type of subframe

`Symbols``ltePUCCH1`

A row vector containing the modulated data symbols (d(0)) for each OFDM symbol

`ltePUCCH1DRS`, `ltePUCCH2DRS`, `ltePUCCH3DRS`

A row vector containing the modulated data symbols (z) for each OFDM symbol

`ltePUCCH2`, `ltePUCCH3`

A row vector containing the modulated data symbols (d) for each OFDM symbol

`TDDConfig`

0, 1 (default), 2, 3, 4, 5, 6

`TimeWindow`

Size of window in resource elements used to average over time during channel estimation

`TimingOffset`

PRACH timing offset, in microseconds

`TMN`

Test model number, as specified in TS 36.141, identifying the test model to use when generating the waveform

`TotSubframes``lteDLPerfectChannelEstimate`, `lteRMCDL`, `lteRMCDLTool`, `lteRMCUL`, `lteRMCULTool`, `lteULPerfectChannelEstimate`

Total number of subframes to generate

`ltePRACHInfo`

The number of subframes duration of the PRACH. Each subframe lasts 30,720 fundamental periods; therefore, `TotSubframes` is ceil(sum(Fields)/30720), the number of subframes required to hold the entire PRACH waveform. The duration of the PRACH is a function of the Preamble Format as described in table 5.7.1-1 of TS 36.211.

`TrBlkSizes`

Transport block sizes for each subframe in a frame

`TxComb` 0, 1

Transmission comb. Controls SRS positions; SRS is transmitted in 6 carriers per resource block on odd (1) and even (0) resource indices.

`TxScheme`

`'Port0'`, `'TxDiversity'`, `'CDD'`, `'SpatialMux'`, `'MultiUser'`, `'Port5'`, `'Port7-8'`, `'Port8'`, `'Port7-14'`.

PDSCH transmission scheme, specified as one of the following options.

Transmission schemeDescription
`'Port0'`Single antenna port, port 0
`'TxDiversity'`Transmit diversity
`'CDD'`Large delay cyclic delay diversity scheme
`'SpatialMux'`Closed loop spatial multiplexing
`'MultiUser'`Multi-user MIMO
`'Port5'`Single-antenna port, port 5
`'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

`Velocity``lteHSTChannel`

Train velocity, in kilometers per hour

`W``lteDMRS`

`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.

`Windowing``lteOFDMModulate`, `lteOFDMInfo`, `lteRMCDL`, `lteTestModel`

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