System object: comm.RBDSWaveformGenerator
Package: comm

Generate RDS/RBDS waveform


y = step(rbdsgen)



Alternatively, 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(rbdsgen) outputs a frame of the baseband RDS/RBDS waveform in column vector y. The waveform contains the number of 104-bit groups, specified in the GroupsPerFrame property of the object. Each symbol is oversampled according to the SamplesPerSymbol property. Thus, the output length is SamplesPerSymbol × 104 × GroupsPerFrame samples. The object uses an internal scheduler to determine the order and frequency of the transmitted group types.


rbdsgen 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.
