Y = step(H,X)
Y = step(H,X) modulates input data, X, with the BPSK modulator System object™, H. It returns the baseband modulated output, Y. The input must be a column vector of bits. The data type of the input can be numeric, logical, or unsigned fixed point of word length 1 (fi object).
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.
