Reconfigurability and low complexity are the two key requirements for finite impulse response (FIR) filters employed in multi standard wireless communication systems. In this article, a comparative study of various adaptive filter architectures, which includes BCSE architecture, constant shift method, programmable shift method, multiple constant method, DA based method are presented. This paper aims at study on efficient adaptive filter architecture in terms of area, EPS (energy per sample) and power. By comparing various methods it is observed that MCM structure involves significantly less area delay product and less energy per sample than the existing block implementation methods of direct- form structure for medium or large filter lengths. The MCM structure involves 14% less ADP and 13% less EPS than that of the existing direct- form block FIR structure.
