Demodulate using OQPSK method

Syntax

Y = step(H,X)

Description

Y = step(H,X) demodulates data, X, with the OQPSK demodulator object, H, and returns Y. Input X must be a double, single, or signed fixed-point data type scalar or column vector. The object produces one output symbol for each pair of input samples. When used with the OQPSK modulator object, the step method output has a one symbol delay as compared to the input of the modulator. Depending on the BitOutput property value, output Y can be integer or bit valued.

    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.
