pre6GSymbolModulate

R2026b

Pre-6G symbol modulation

Since R2026b

Syntax

sym = pre6GSymbolModulate(ch,cw)

sym = pre6GSymbolModulate(___,OutputDataType=odt)

Description

Add-On Required: This feature requires the 6G Exploration Library for 5G Toolbox add-on.

sym = pre6GSymbolModulate(ch,cw) maps scrambled bits to complex modulation symbols for 6G research and prototyping. The function uses the modulation scheme specified by ch.

sym = pre6GSymbolModulate(___,OutputDataType=odt) additionally specifies the data type of the modulated output symbols.

Examples

Modulate Pre-6G Scrambled Bits

Create a carrier configuration object with default parameters and a physical channel configuration object with 16-QAM modulation.

carrier = pre6GCarrierConfig;
ch = pre6GPhysicalChannelConfig(Modulation="16QAM");

Generate random bits for a batch size of three and scramble them. The number of bits must be a multiple of Qm (4 for 16-QAM).

bits = randi([0 1],480,3,"int8");
cw = pre6GScramble(carrier,ch,bits);

Modulate the bits to complex symbols.

sym = pre6GSymbolModulate(ch,cw);

Verify the output length equals the number of input bits divided by Qm.

isequal(length(sym),length(cw)/ch.Qm)

Input Arguments

ch — Physical channel configuration parameters

pre6GPhysicalChannelConfig object

Physical channel configuration parameters, specified as a pre6GPhysicalChannelConfig object. This function uses only the Modulation, Constellation, and Qm properties of the pre6GPhysicalChannelConfig object.

cw — Codeword bits to modulate

real matrix

Codeword bits to modulate, specified as a real matrix of size G-by-B, where G is the codeword length and B is the batch size. G must be a multiple of Q_m (the modulation order).

Data Types: double | int8 | logical

odt — Output data type

"single" (default) | "double"

Output data type, specified as "single" or "double".

Data Types: char | string

Output Arguments

sym — Modulated symbols

complex matrix

Modulated symbols, returned as a complex matrix of size (G / Q_m)-by-B, where G is the codeword length, Q_m is the modulation order, and B is the batch size.

Data Types: single | double
Complex Number Support: Yes

Extended Capabilities

GPU Arrays

Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox™.

The pre6GSymbolModulate function fully supports GPU arrays. To run the function on a GPU, specify the input data as a gpuArray (Parallel Computing Toolbox). For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
