System object: comm.GMSKModulator
Package: comm

Modulate using GMSK method


Y = step(H,X)


    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 GMSK modulator object, H. It returns the baseband modulated output in Y. Depending on the BitInput property value, input X can be a double precision, signed integer, or logical column vector. The length of vector Y is equal to the number of input samples times the number of samples per symbol that you specify in the SamplesPerSymbol property.

    Note:   H 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 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.
