Latest Patents

Junjie Zhu holds a patent for "Methods and apparatus for reducing signal degradation." This invention involves a single frequency relay station that receives a signal from a master station and retransmits it. Before retransmitting, the relay station employs a digital filter to eliminate signal components caused by multipath interference and coupling interference. The coefficients for the digital filter are derived from the characteristics of the multipath interference and the overall transfer function of the relay station. This is achieved by temporarily turning off the retransmission to estimate the multipath interference from the received signal, followed by resuming retransmission to determine the transfer function. A simplified inverse fast Fourier transform is utilized to streamline the calculations. Junjie Zhu has 1 patent to his name.
