Border Effect Removal for IFIR and Interpolated Volterra Filters

This paper presents a procedure to remove the border effect from interpolated finite impulse response (IFIR) and interpolated Volterra adaptive filters using the LMS algorithm. The used approach permits to reduce the steady-state mean-square error (MSE) of such structures. In situations that the border effect is important, the obtained improvement is noticeable. In addition, the computational burden required to implement such a procedure is slight. Simulation results confirm the effectiveness of the proposed approach.
