Title: Innovations by Qifa Wu in Radio Technology
Introduction
Qifa Wu is a notable inventor based in Beijing, China, recognized for his contributions to radio technology. With a total of three patents to his name, Wu has made significant advancements in the field of frequency modulation and radio transmission.
Latest Patents
One of Wu's latest patents is a radio transmitter and radio receiver with channel condition assessment. This innovation addresses the common issue of signal interference between FM radio transmitters and existing FM radio station broadcasts. The invention incorporates a scan system that quickly identifies a vacant channel for the FM radio transmitter to use. This system measures both on-channel and out-of-channel signal quality, selecting the best channel for transmission based on these measurements. Additionally, the scan system is integrated into an FM radio receiver, allowing it to tune to a valid channel efficiently.
Another significant patent is the frequency modulation (FM) clear channel scanning system and method of using the same. This system receives signals from an antenna, dividing the band into sub-bands and scanning each channel to determine a candidate channel based on the lowest figure of merit (FOM). It includes an on-channel selection block that focuses on the on-channel frequencies while disregarding out-of-channel frequencies, thereby generating a FOM on-channel signal that measures the quality of the on-channel signal.
