      Given: The Cheetah CXFT module with data to be run through an FFT

      When: An FFT algorithm is selected with an input data size that the algorithm is not designed for

      Then: The input data shall be reshaped to fit the constraints of the algorithm such that the data output from any of the selected algorithms shall have an output data shape that is independent of the exact algorithm used.

      When called to perform an fft, the framework will now automatically shrink or extend (zero pad) the input data to match the limitations of the active Fft algorithms (as selected by the user). This is done in a felxible/extensible manner that allows the integration of future algos.

      Links to the code and commits can be found under AT4-521, AT4-631, and AT4-632

    Description

      Some of the FFT algorithms used within the CXFT module in Cheetah only works on input data with sample number equal to an exact power of 2. In order to ensure that the output data from the CXFT module always have the same size, independent on the exact algorithm used to perform the FFT, the input data will need to be reshaped to have an exact power of 2 number of samples as well.

          Feature - A Feature is a service that fulfills a stakeholder need. Each feature includes a benefit hypothesis and acceptance criteria, and is sized or split as necessary to be delivered by a single Agile Release Train (ART) in a Program Increment (PI). SP-1882 Enhance functionality of PSS Complex Fourier Transform (CXFT) module

          • Should have - Items labelled as "Should have" are important but not necessary for delivery in the current delivery timebox. While "Should have" items can be as important as "Must have", they are often not as time-critical or there may be another way to satisfy the requirement so that it can be held back until a future delivery timebox.
