System object: comm.OFDMDemodulator
Demodulate using OFDM method
Y = step(H,X)
[Y,PILOT] = step(H,X)
Starting in R2016b, instead of using the
step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example,
y = step(obj,x) and
y = obj(x) perform equivalent operations.
Y = step(H,X) demodulates input data,
with the OFDM demodulator System object,
and returns the baseband demodulated output,
The input is a double-precision, real or complex, 2-D matrix of symbols
whose dimensions are a function of the number of subcarriers, the
cyclic prefix length, and the number of receive antennas. You can
determine the dimensions by using the
Y, is a double-precision, complex,
[Y,PILOT] = step(H,X) separates the
PILOT signal on
the subcarriers specified by the PilotCarrierIndices
property value of
H. This syntax applies when the PilotOutputPort property
H is true.
PILOT is a double-precision,
complex, 3-D array.
obj specifies the System object on which to run this
The object performs an initialization the first time the
step method is executed. This initialization locks nontunable properties and
input specifications. For more information on changing property values, see System Design in MATLAB Using System Objects.
