Adaptive interference cancellation is to solve the radiation interference between transmitter and receiver working on the same platform. The outputs of multipliers that are in feedback control module, after integralization and amplification, are to control the electronic-controlled attenuator. Because of zero drifts of multipliers and limitation of linearity range of electronic-controlled attenuators,...
The interference cancellation can restrain the strong interference between high power transmitter and receiver. The main point is to make sure the time delay between interference signal and reference signal match. The paper researches on the influence of time delay to the interference cancellation system. When the interference signal is single frequency signal, the ICR is unrelated with the time delay...
The paper improves a new method to set up the high frequency circuit model based on scattering parameters equal division. At first, divide the measured scattering parameters of two-port network equally for several times so that the two-port network can be presented as the sub-networks connected in series. Then transform the divided scattering parameters into admittance parameters, and establish π-type...
