System object: comm.PSKTCMDemodulator
Demodulate convolutionally encoded data mapped to M-ary PSK constellation
Y = step(H,X)
Y = step(H,X,R)
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 the PSK modulated
X, and uses the Viterbi algorithm to
decode the resulting demodulated, convolutionally encoded bits.
be a complex, double or single precision column vector. The
outputs a demodulated, binary data column vector,
When the convolutional encoder represents a rate K/N code,
the length of the output vector is KL,
where L is the length of the input vector,
Y = step(H,X,R) resets the decoder to the
all-zeros state when you input a reset signal,
R must be a double precision or logical,
scalar integer. This syntax applies when you set the

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.
