Design and implementation of single order LMS based adaptive system identification on altera based cyclone II FPGA

Abstract

Identification is a genuine fact that resembles in any kind of systems, whether it may be a control, compute or communication systems. System identification is a proposed area that establish the mathematical model of the system which helps for modeling and identification of an unknown system. This paper is focused on design and synthesis of Adaptive System Identification based on LMS algorithm with ALTERA QUARTUS II development platform and implemented on CYCLONE II EP2C35F672C8 Field Programming Gate Array (FPGA). Architecture of adaptive filter that is based on multiplier and adder is to realize the MAC operation of the Finite Impulse Response (FIR). The coefficients of the adaptive filter are adjusted automatically by Least Mean Square (LMS) algorithm based on input signals. For this cause adaptive filter is more important for system identification. The design is also experienced in Model based Design approach with the help of Xilinx System Generator for the application of Adaptive System Identification.
