Latest Patents
Youjian Liu holds a patent titled "Methods of controlling data rate in wireless communications systems." This patent outlines a method where a received data packet is decoded to determine a packet error rate value. An average packet error value for N received data packets is updated based on this determined packet error rate value. The updated average packet error rate value is then compared against a threshold value, and a data rate request is issued based on this comparison. Additionally, the method includes receiving a response to a transmitted data packet, which relates to an average packet error rate value. The average packet error rate value is compared against a threshold, and a data rate is modified based on this comparison. The method also allows for dynamic adjustments of a data rate control margin to overcome channel estimate errors resulting from transmission delays, optimizing system resources in real time.
