Title: Innovations by Qingyi Zheng
Introduction
Qingyi Zheng is an accomplished inventor based in Newark, CA (US). He has made significant contributions to the field of communications technology, holding a total of 4 patents. His work focuses on enhancing the performance of legacy communications networks through innovative encoding and error correction systems.
Latest Patents
One of his latest patents is an "Encoding and error correction system for enhanced performance of legacy communications networks." This system includes a header stripper that removes header data from multiple legacy system frames. Each frame adheres to a legacy system frame format and consists of a header block and a traffic channel block. A first encoder encodes speech data for several slots of the traffic channel blocks, while a second encoder encodes the stripped header data as a frame header. The system combines the frame header and encoded speech data to generate a frame, which is then segmented into multiple segments for transmission as traffic channel data.
Another notable patent is also titled "Encoding and error correction system for enhanced performance of legacy communications networks." This invention employs an adaptive multi-rate (AMR) codec to strip header data from legacy system frames. The speech data is encoded using the AMR to create bits for a data block similar to those in the original frames. The stripped header data is encoded as a long frame header using a fixed convolution coder. The speech data undergoes convolutional encoding, and the long frame header is combined with the encoded speech data to form a long frame, which is then deconstructed into equal segments for transmission.
