Latest Patents

Chang-Tsou Liu holds a patent for an "Efficient data storage arrangement for far-end echo canceller." This invention presents an efficient data storage scheme for an echo canceller used in high-speed modems. The patent outlines a method of storing unencoded words of lesser length in bits, which results in substantial memory savings. For instance, in a v.32terbo modem operating at 19,200 bps, the unencoded word consists of only eight bits compared to nine bits for the trellis-encoded codeword. This allows one memory word (16 bits) to store two unencoded words, achieving a 50% reduction in memory usage.
