Latest Patents

One of his latest patents is an "Echo cancellation method and transceiver." This invention aims to reduce the dependence of a system on the effective number of bits (ENOB) of a digital-to-analog converter (DAC) while improving the performance of echo cancellation. The transceiver includes an echo cancellation apparatus, a transmit link, a receive link, and a hybrid circuit. The transmit and receive links are coupled to a transmission line using the hybrid circuit. The echo cancellation apparatus consists of a first signal converter, a slicer, a first subtractor, a second digital-to-analog converter, a second subtractor, and a third subtractor.

Another notable patent is the "Narrowband interference isolation method and communication apparatus." This application provides a method for isolating narrowband interference. The method includes determining a parameter of a narrowband interference signal and calculating a coefficient for a first filter based on this parameter. The first filter is located at the receive end of a master communication device, which is connected to multiple slave communication devices. The parameter or coefficient is sent to these slave devices using an Ethernet operation, administration, and maintenance (OAM) frame.
