Latest Patents

One of Yan Li's latest patents is focused on window position optimization for a pilot-aided OFDM system. This invention discloses a method of reducing aliasing in an OFDM system by utilizing window optimization and pilots. The process involves receiving an RF signal that includes a pilot, generating a channel frequency response estimate, and dynamically selecting a window to capture a channel impulse response to prevent aliasing.

Another notable patent by Yan Li addresses I/Q imbalance compensation. This invention describes a zero-IF direct-conversion OFDM receiver that estimates and corrects an I/Q imbalance in a baseband signal. The receiver performs complex down-conversion on a received signal, dividing it into In-phase (I) and Quadrature-phase (Q) signals. An I/Q compensation algorithm estimates the imbalance factors and applies them to recover the signal of interest.
