Title: Jiwu Liu: Innovator in Communication Technology
Introduction
Jiwu Liu is a prominent inventor based in Shanghai, China, known for his contributions to communication technology. He holds three patents that showcase his innovative approach to service processing methods and frequency estimation in telecommunications.
Latest Patents
One of Jiwu Liu's latest patents is a service processing method, a baseband processor chip, and a terminal. This invention outlines a method for processing a circuit-switched (CS) domain service while managing packet-switched (PS) domain data. The method identifies whether the PS domain data is critical for maintaining the quality of service (QoS) level. If the data is not critical, the processing of the PS domain service is suspended to prioritize the CS domain service. This innovation allows terminals to efficiently handle multiple service types simultaneously.
Another significant patent is a method for carrier frequency offset fine estimation in a TD-SCDMA system. This method provides a simple and efficient approach to estimating frequency offsets by analyzing the phase drift of a synchronization code. By subtracting the QPSK modulation phase from the received phase, the frequency offset can be accurately computed, enhancing the performance of communication systems.
