nrSSSIndices

Generate SSS resource element indices

Description

example

ind = nrSSSIndices returns the resource element indices for the secondary synchronization signal (SSS), as defined in TS 38.211 Section 7.4.3.1 [1]. The returned indices are one-based using linear indexing form. This indexing form can directly index the elements of a 240-by-4 matrix corresponding to the Synchronization Signal / Physical Broadcast Channel (SS/PBCH) block. The order of the indices indicates how the SSS modulation symbols are mapped.

ind = nrSSSIndices(Name,Value) specifies index formatting options by using one or more name-value pair arguments. Unspecified options take default values.

Generate the 127 resource element indices associated with the SSS within a single SS/PBCH block.

ind = nrSSSIndices
ind =

    127×1 uint32 column vector

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'IndexStyle','subscript','IndexBase','0based' specifies nondefault resource element index formatting options.

Resource element indexing form, specified as the comma-separated pair consisting of 'IndexStyle' and one of these values:

  • 'index' — The indices are in linear index form.

  • 'subscript' — The indices are in [subcarrier, symbol, antenna] subscript row form.

Data Types: char | string

Resource element indexing base, specified as the comma-separated pair consisting of 'IndexBase' and one of these values:

  • '1based' — The index counting starts from one.

  • '0based' — The index counting starts from zero.

Data Types: char | string

Output Arguments

collapse all

SSS resource element indices, returned as one of these values:

  • Column vector — When 'IndexStyle' is 'index'.

  • M-by-3 matrix — When 'IndexStyle' is 'subscript'. The matrix rows correspond to the [subcarrier, symbol, antenna] subscripts based on the number of subcarriers and OFDM symbols in an SS/PBCH block, and the number of antennas, respectively.

Depending on 'IndexBase', the indices are either one-based or zero-based.

Data Types: uint32
