Latest Patents
One of Yuxian Zhang's latest patents is a method of large frequency offset estimation for an OFDM communications system using reference signals. This method involves performing carrier frequency offset (CFO) estimation of physical channels in a mobile communications system. It includes steps for channel estimation of a received signal based on multiple orthogonal frequency division multiplex (OFDM) symbols in one or more reference signals. The method determines multiple phase rotation values and corresponding time differences between different OFDM symbols to obtain a first CFO estimation candidate. Additionally, the base phase rotation range is extended to provide further CFO estimation candidates within a broader range.
Another notable patent is the multi-layer bandpass filter. This invention comprises a bandpass filter with a multi-layered body, featuring a first resonator conductor on the first layer and a second resonator conductor on a lower layer. The design includes a first coupling area formed by a partial overlap of the two resonator conductors, with specific lengths tailored to the center wavelength of the bandpass filter passband.
