Latest Patents

Wu's latest patents include a "Method and apparatus for fractal-excited linear predictive coding" and a "System and method for modeling discrete data sequences." The first patent describes a method for encoding and decoding digital signals by separating the original signal into linear and nonlinear portions. The linear portion is encoded using linear predictive coding (LPC) techniques, while the nonlinear portion is encoded using a fractal transform. This innovative approach allows for the generation of decoded digital signals through a systematic process involving LPC filter coefficients and fractal transform coefficients.

The second patent focuses on an encoder and decoder system for compressing discrete data sequences. It features a self-affine map generator and a backward adaptive map generator that model source vectors formed from discrete data sequences. The system evaluates mapping functions based on collage errors and distance measurements, ultimately selecting the most effective mapping function for data representation. The decoder employs both iterative and backward decoding methods to synthesize vectors from the mapping functions received from the encoder.
