Latest Patents

Xiaoqiang Ma holds a patent titled "Expectation-maximization-based channel estimation and signal detection for wireless communications systems." This invention provides a system and method for detecting symbols of a modulated signal received via multiple channels in a wireless communications system. The process begins with an initial estimation of a transmitted symbol based on channel estimates derived from either pilot symbols or previously estimated symbols. The channel estimate is then updated, and the next symbol estimate is computed by maximizing the expectation of the log likelihood function. This iterative process continues until the estimates converge, ensuring accurate symbol detection.
