step

System object: comm.RaisedCosineTransmitFilter
Package: comm

Output interpolated values of input signal

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) outputs the interpolated values, Y, of the input signal X. The System object treats the input matrix Ki-by-N as N independent channels. The object interpolates each channel over the first dimension and then generates a Ko-by-N output matrix. In the output matrix, Ko = Ki*L, where L represents the output samples per symbol. The object supports real and complex floating-point inputs.

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.
