Latest Patents

Li Li holds a patent for an "Angular domain channel estimation method based on matrix reconstruction for symmetrical nonuniform array." This method combines a two-stage channel estimation and channel equalization scheme based on a Symmetrical Nonuniform Linear Array (SNLA) model. In the first stage, a matrix reconstruction method is employed to estimate the angle of arrival (AOA) of a path. Compared to traditional channel estimation methods based on Uniform Linear Arrays (ULA), this matrix reconstruction method achieves a higher resolution ratio. In the second stage, a Least Squares (LS) method is utilized to obtain the path gain. The angular domain channel estimation method significantly reduces the mean square error of channel estimation, bit error rate of data transmission, and the complexity associated with traditional schemes. Simulation results indicate that this method can achieve lower mean square error (MSE) and bit error rate (BER) compared to traditional methods.
