Latest Patents

Yanyan Wang's latest patents include an "Angular domain channel estimation method based on matrix reconstruction for symmetrical nonuniform array." This invention presents a two-stage channel estimation and channel equalization scheme based on a symmetrical nonuniform array (SNLA) model. The first stage employs a matrix reconstruction method to estimate the angle of arrival (AOA) of a path, achieving a higher resolution ratio compared to traditional methods based on uniform linear arrays (ULA). The second stage utilizes a least squares (LS) method to determine the path gain. This method significantly reduces the mean square error (MSE) of channel estimation, bit error rates (BER) of data transmission, and the complexity associated with traditional schemes. Simulation results indicate that her method outperforms conventional techniques in terms of MSE and BER.

Another notable patent is for a "Blend of aromatic polycarbonate and polylactic acid, the method for preparing the same and the use thereof." This invention involves a blend that enhances compatibility between aromatic polycarbonate and polylactic acid through the addition of a transesterification catalyst during the preparation process. The resulting blend exhibits excellent mechanical properties, thermal processability, and flame retardance, making it suitable for various applications, including mechanical products, electronic equipment, and construction materials.
