| Abstract(in English) | Along with the increasing rate of data transmission, the demand for the adaptive equalizer, which effectively eliminates the Inter Symbol Interference(ISI), has increased. Especially, since the blind equalization has no necessity of training sequences which is indispensable for LMS and DFE, it is desirable for its capability to effective on variety of appliances. However, the conventional blind equalization systems suffers from several problems, e.g., existence of local minimum, slowness rate of convergence, impropriety for real-time processing. In this paper, we show a new blind identification algorithm solving the problems mentioned above. The proposed blind system identification algorithm which is based on second-order statistics and exploits a Single-Input Double-Output(SIDO)model. It is suitable for real-time processing system because of lower operation and high-speed convergence. At first, we refer to the general description of SIDO model and propose our new cost function. We show the equation which is derived from a new cost function has the uniqueness of solution. Then, we develope an algorithm to solve the equation above recursively and verify its efficiency by computer simulation. |
