Latest Patents

Qiyan Fan's latest patents include a multi-channel radio frequency transceiving device and method. This device comprises an optical module, a digital signal processing module, a radio frequency transceiving module, a downlink module, and a microprocessing module. The optical module receives an optical signal corresponding to baseband data, converts it into an electric signal, and outputs this signal to the digital signal processing module. The digital signal processing module then obtains the baseband data and channel number information based on the electric signal, allowing for the allocation and processing of the baseband data. The microprocessing module determines the number of working channels of the radio frequency transceiving module, the corresponding number of working channels of the downlink module, and the downlink output power based on the channel number information and baseband data, while closing the remaining channels in the downlink module.

Another significant patent is the analog pre-distortion processing circuit and signal processing device. This circuit includes a narrowband spread spectrum module, an analog pre-distortion module, and a filtering module. The narrowband spread spectrum module spreads an input narrowband radio frequency signal into a broadband radio frequency signal with a preset bandwidth. The analog pre-distortion module performs analog pre-distortion linearization processing on the broadband radio frequency signal to obtain a linearized broadband radio frequency signal. The filtering module then filters the linearized broadband radio frequency signal to produce a linearized narrowband radio frequency signal.
