Memory Optimization in Adaptive FIR Filter Using APC-OMS

An efficient architecture for the implementation of Adaptive FIR Filter for achieving optimized memory and increased accuracy. Besides, we have described the Adaptive FIR filter where filter coefficients are frequently updated in order to minimize the error out. The combined Anti-symmetric Product Coding (APC) and Modified Odd Multiple Storage (OMS) technique to achieve the reduction of LUT size to Third-fourth of the conventional technique. The APC-OMS based Filter design to reduce the LUT size and the errors are eliminated at the output of the adaptive fir filter. Simulation results show good accuracy of the input signal.
