There is the over-sampling method which is one of the methods for realizing the blind identification. In the conventional method, the unknown system is usually assumed by FIR system and the estimation filter is also used by FIR filter. However, if a target system has long impulse length in many real environment, we may have to assume IIR system for the unknown system. If we use FIR filters to estimate such systems, the identification performance is lower. Therefore, it is necessary to research the blind identification method for the unknown system as IIR system. Then, we propose the blind identification based on over-sampling method using orthogonal filter for IIR system and we evaluate the identification performance by computer simulations.
