  • Abstract
    Instead of using the FFT, all the real joint time-frequency transformations (JTFT) can be evaluated by the same efficient transformation algorithm, using different time-indexed autocorrelation functions. The approach presented dramatically reduces the computation load. Research suggests that a software package or a custom VLSI chip may implement real JTFTs.
