System object: comm.PSKTCMModulator
Convolutionally encode binary data and map using M-ary PSK constellation
Y = step(H,X)
Y = step(H,X,R)
Y = step(H,X) convolutionally encodes and modulates the input binary data column vector, X, and returns the encoded and modulated data, Y. X must be of data type numeric, logical, or unsigned fixed point of word length 1 (fi object). When the convolutional encoder represents a rate K/N code, the length of the input vector, X, must be K L, for some positive integer L. The step method outputs a complex column vector, Y, of length L.
Y = step(H,X,R) resets the encoder of the PSK TCM modulator object to the all-zeros state when you input a reset signal, R, that is non-zero. R must be a double precision or logical scalar integer. This syntax applies when you set the ResetInputPort property to true.
Note: The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object™ issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
