lteSymbolModulate
Symbol modulation
Description
Examples
Generate QPSK Modulated Symbols
Map bit values to QPSK modulated symbols.
out = lteSymbolModulate([0; 1; 1; 0], 'QPSK')
out = 2×1 complex
0.7071 - 0.7071i
-0.7071 + 0.7071i
Input Arguments
in
— Input bits
column vector | cell array
Input bits, specified as a column vector, where each bit is either 0
or
1
. The vector length must be a multiple of two for
QPSK, four for 16-QAM, six for 64-QAM, eight for 256-QAM, or ten for
1024-QAM. The bit values must be 0 or 1.
Alternatively, specify in
as a cell array
containing one bit vector or a cell array containing two bit vectors.
Data Types: double
| cell
mod
— Modulation scheme
'BPSK'
| 'QPSK'
| '16QAM'
| '64QAM'
| '256QAM'
| '1024QAM'
| cell array
Modulation scheme, specified as 'BPSK'
, 'QPSK'
,
'16QAM'
, '64QAM'
,
'256QAM'
, or '1024QAM'
.
Alternately, you can specify mod
as a cell
array of one or two modulation schemes. The number of modulation schemes
in mod
cannot exceed the number of bit vectors
specified by in
. If in
specifies two bit
vectors and mod
specifies one modulation scheme,
the same modulation is used for both bit vectors.
Data Types: char
| cell
Output Arguments
out
— Complex modulated output symbols
column vector
Complex modulated output symbols, returned as a column vector.
The symbols use the modulation scheme specified in mod
.
Data Types: double
Complex Number Support: Yes

Introduced in R2014a
