With a total of four patents to his name, his work focuses on enhancing the performance of communication systems.
Latest Patents
Yunxin Li's latest patents include two innovative inventions. The first is related to the estimation of signal to noise ratio in receivers. This invention addresses the estimation of signal to noise ratio (SNR) at a communications receiver, which is particularly suited for Orthogonal Frequency Division Multiplexing (OFDM) receivers. The method involves estimating the power ratio between the noise and the combined signal and noise, and averaging this value over a time interval.
The second patent concerns the soft-demapping of Quadrature Amplitude Modulation (QAM) signals. This invention enables soft-decision channel decoding in a communications system. The method includes extracting baseband signals, sampling them to obtain complex numbers, converting these to frequency domain vectors, and approximating bit log-likelihood ratios for each symbol. This process enhances the efficiency of soft-decoding channel codes.
