Abstract
In HINOC system, we use OFDM multi-carrier modulation which is highly sensitive to single-frequency interference. In this paper, notch filter is used to resist such interference. We propose a method to determine the coefficient of the zero-pole IIR notch filter and use the improved zero-pole algorithm with least squares approximation criteria to optimize the pole position of notch filter, so that it has symmetrical and controllable pass-band gain. This method has low complexity, good notch performance, higher processing precision and, therefore, better practical value. Simulations prove the validity of the technique in HINOC system.
