Latest Patents

Orling's latest patents include "Computationally efficient analysis and synthesis of real signals using discrete Fourier transforms and inverse discrete Fourier transforms." This invention significantly reduces the number of complex computations required to compute a DFT or IDFT when a pattern is identified in an original input data sequence. By modifying the data sequence, the size of the sequence to be transformed is reduced. The DFT (IDFT) is then performed on this modified input data sequence, generating a transformed sequence. The transformed data sequence is manipulated to produce an output sequence that corresponds to the DFT (IDFT) of the original input data sequence without needing to calculate the DFT (IDFT) of the entire original input data sequence. The invention employs three symmetrical patterns to simplify and enhance the efficiency of DFT and IDFT computations: Hermite symmetry, index-reversed, complex-conjugate symmetry, and mirror symmetry. This computational reduction increases signal processing speed and decreases power consumption, which are highly desirable attributes in virtually every DFT/IDFT application.

Another significant patent is "Method and apparatus for efficient computation of discrete Fourier." This invention also reduces the number of complex computations necessary for DFT and IDFT operations. It allows both operations to be computed using the same device, optimizing the computation for maximum efficiency. The DFT operation is performed on an N-point sequence on one data processing path, while the IDFT operation is executed on another path using the same N-point fast Fourier transform (FFT).
