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 = 127×1

Extended Capabilities

C/C++ Code Generation

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

Usage notes and limitations:

The datatype input argument must be compile-time constant. For example, when specifying 'single' as the output data type, include {coder.Constant('OutputDataType'),coder.Constant('single')} in the -args value of the codegen function. For more information, see the coder.Constant (MATLAB Coder) class.
