step

System object: comm.PSKModulator
Package: comm

Modulate using M-ary PSK method

Syntax

Y = step(H,X)

Description

Note

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) modulates input data, X, with the PSK modulator System object, H. It returns the baseband modulated output, Y. Depending on the value of the BitInput property, input X can be an integer or bit valued column vector with numeric, logical, or fixed-point data types.

Note

obj specifies the System object on which to run this step method.

The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties (MATLAB) 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.
