Latest Patents

Limei Wei's latest patents include a "Method of double weighting parallel interference cancellation" and a "Method of parallel interference cancellation and an apparatus thereof." The first patent presents a method for double weighting parallel interference cancellation in CDMA mobile communication systems. This method integrates concepts from both partial weighting and Bayes rule-based weighting. It calculates the reliability coefficient of decision results for user symbols and applies a weighting algorithm to regenerate signals. The process involves estimating and removing multiple address interference (MAI) by obtaining MAI from weighted regenerated signals of other users, ultimately enhancing the clarity of the expected user's signal.

The second patent outlines a method for parallel interference cancellation (PIC) in mobile communication systems. This method processes user signals through multiple stages of PIC to partially remove MAI. It includes multipath de-spreading and combines results from different stages to improve the signal-to-noise ratio (SNR) of the output user signal. A PIC device is also provided to facilitate this method, demonstrating Wei's commitment to advancing mobile communication technology.
