Latest Patents

One of his latest patents is titled "System and method for time saving cell search for mobile devices in single and multiple radio technology communication systems." This invention involves a cellular device with a stacked protocol, which includes an upper layer and a lower layer. The lower layer features a multiple carrier detection unit, a memory, and a digital processing system. The multiple carrier detection unit receives various wireless carrier signals and generates corresponding output digital streams. The memory stores a target cell search list, while the digital processing system processes the digital streams in parallel based on parameters within the target cell search list, such as frequency indicators and radio access technology (RAT) indicators.

Another significant patent by Gao is "Method and encoder for bit-rate saving encoding of audio signals." This invention focuses on MPEG 1 audio data compression using subband coding. It employs a psychoacoustic model that adapts to the masking behavior of human hearing. The quantization process ensures that the quantization noise introduced by the coding does not exceed the masking curve for each subband. The output from the psychoacoustic models results in a set of Signal-to-Masking Ratios (SMR) for every subband.
