Latest Patents

One of his latest patents is the "Symbol boundary detection device and method for use in OFDM system." This invention provides a symbol boundary detection device and a method for use in a receiver of a multi-channel communication system. The device utilizes a threshold to make an auxiliary judgment to select a proper symbol boundary reference point within an early range. The threshold can be flexibly set in response to different characteristics of the systems. Additionally, a pilot symbol guard interval matched filter is utilized to determine whether a pilot symbol guard interval is received.

Another significant patent is the "Automatic gain control and antenna selection method for a radio communication system." This invention offers an automatic gain control and antenna selection method used in a receiver of a radio communication system. The received signal power is estimated by digital signal processing after analog-to-digital conversion in the system. This process adjusts the gain of the front-end analog signal until the magnitude of the analog signal is optimized for digital signal processing. Furthermore, the ADC is utilized to estimate the signal power as the basis for antenna selection.
