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 1-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.

Examples

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

ind = nrSSSIndices
ind = 127x1 uint32 column vector

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

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

RE indexing form, specified as 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

RE indexing base, specified as one of these values:

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

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

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 1-based or 0-based.

Data Types: uint32
