Title: The Innovations of Chunqing Zhang
Introduction
Chunqing Zhang is a notable inventor based in Bristol, GB. He has made significant contributions to the field of signal processing and interference cancellation. His innovative work has led to the development of a unique patent that addresses challenges in signal isolation and interference management.
Latest Patents
Chunqing Zhang holds a patent for an "Active interference cancellation apparatus, signal isolation control apparatus and method of actively cancelling interference." This apparatus includes a receiver chain with an input node and a transmitter chain comprising a tap and output nodes. An auxiliary transmitter chain is also included, which features an auxiliary input node coupled to the tap node, an adaptive filter unit, and a signal output connected to the input node. The filter unit consists of an interpolation processor, an adaptive filter, and a coefficient processor linked to the receiver chain and the adaptive filter. The transmitter chain generates a first waveform that comprises a plurality of frequency-separated signals. Simultaneously, the auxiliary chain applies a second waveform that includes another set of frequency-separated signals at the input node. The receiver chain then receives a composite waveform that combines a waveform from the output node and the second waveform. Notably, the first waveform lacks signals necessary for determining the coefficients of the filter, whose frequencies coincide with the signals of the second waveform.
