This paper applies the adaptive active noise control (AANC) in cancelling the noise of amorphous alloy core transformer. The on-line identification of error channel is used to denoise, because the off-line identification of error channel will not fit the uncertainty of the error channel in the control system. The simulation results show that the AANC technology to control the noise of the amorphous...
In this paper, we propose two algorithms to improve the rate-distortion performance and reduce the computational complexity, respectively. Due to the observation that content does not change dramatically from frame to frame in majority of cases and the effect of aliasing stays almost constant between consecutive frames, we assume that adaptive filters for the previous frame could accurately compensate...
