nrSSS

Generate SSS symbols

Syntax

sym = nrSSS(ncellid)

sym = nrSSS(ncellid,'OutputDataType',datatype)

Description

sym = nrSSS(ncellid) returns the secondary synchronization signal (SSS) symbols for the physical layer cell identity number ncellid. The function implements TS 38.211 Section 7.4.2.3 [1].

sym = nrSSS(ncellid,'OutputDataType',datatype) specifies the data type of the SSS symbol.

Examples

Generate SSS Symbols

Generate the sequence of 127 SSS binary phase shift keying (BPSK) modulation symbols for a given cell identity. The SSS is transmitted in the third symbol of a Synchronization Signal / Physical Broadcast Channel (SS/PBCH) block.

ncellid = 17;
sss = nrSSS(ncellid)

sss =

   -1
    1
   -1
   -1
   -1
    1
    ...

Input Arguments

ncellid — Physical layer cell identity number

integer

Physical layer cell identity number, specified as an integer from 0 to 1007.

Data Types: double

datatype — Data type of output symbols

'double' (default) | 'single'

Data type of the output symbols, specified as 'double' or 'single'.

Data Types: char | string

Output Arguments

sym — SSS symbols

column vector of real numbers

SSS symbols, returned as a column vector of real numbers.

Data Types: single | double

Extended Capabilities

C/C++ Code Generation

Generate C and C++ code using MATLAB® Coder™.

Usage notes and limitations:

Names and values in name-value pair arguments must be compile-time constants. For example, to specify single data type for the output, include {coder.Constant('OutputDataType'),coder.Constant('single')} in the -args value of codegen. For more information, see coder.Constant.
