Implementation of high-order FIR digital filtering for software defined radio receivers
Arunadevi Jawahar, P. Pushpa Latha · 2016
The high-speed FIR filters are needed in the channelizer of software defined radio (SDR) receiver. In this paper, we investigate the feasibility of realizing block Finite Impulse Response (FIR) filter in transpose structure configuration for effective area-delay realization of large order FIR filters for reconfigurable applications. The performances of both existing and proposed structures are compared. The delay for the proposed structure has been reduced as the filter order increases. The max frequency for the proposed structure has greatly increased compared to the existing reconfigurable FIR filter structure.
