Latest Patents

Feng's latest patent is titled "Method and apparatus for compressing a digital signal using vector." This innovative approach involves an improved Vector Quantization (VQ) system that compresses digital signals by dividing them into a series of segments. Each segment consists of multiple signal values. The system utilizes two tables of vector values, known as the class-1 table and the class-2 table, which have varying degrees of signal correlation. For each selected segment, the VQ system calculates two vectors, Xbar1 and Xbar2, which represent differences between the signal values and their averages in preceding and current segments, respectively. By determining the best match entries from both tables, the system can effectively insert an identifying code or compressed signal into the compressed signal stream.
