Power Efficient and High Throughput of Fir Filter Using Block Least Mean Square Algorithm in Fpga

In silicon on chip technology demands high performance and low power Very Large Scale Integrated Circuit (VLSI) digital signal processing (DSP) systems. The aim of this paper explores the power consumption technique for the architecture of Finite Impulse Response (FIR) adaptive filter. An adaptive FIR filter with Block Least Mean Square (BLMS) algorithm was developed to reduce the power. Distri...

Finite Impulse Response ( FIR ) Filters

Systolic FIR filter Based FPGA

In this paper, we first review in detail the basic building blocks of reconfigurable devices, essentially, the fieldprogrammable gate arrays (FPGAs), then we describes a highspeed, reconfigurable, Systolic FIR filter design implemented in the Virtex-II series of FPGAs. The VHDL description of this filter is used for simulation and EDIF for implementation using Xilinx's place and route tools. Th...

FPGA Design of Parallel Linear-Phase FIR Digital Filter Using Distributed Arithmetic Algorithm

Based on fast FIR algorithms (FFAs), we propose distributed arithmetic algorithm based new parallel FIR filter architectures, which are beneficial to symmetric convolutions in terms of the hardware cost. Multipliers are the major portions in hardware consumption for the parallel FIR filter implementation. The proposed new structures exploit the nature of symmetric coefficients of odd length and...

Interference Mitigation of Replay Attacks in GPS Receiver using of Finite Impulse Response Filter

The vulnerability of civil GPS receiver to interference may be intentional or unintentional. Among all types of interference, replay attack intended as the most dangerous intentional one. The signal structure of replay attack is almost the same with the satellite signal. The interference effects can be reduce with the design of an appropriate filter in the receiver. This paper presents two meth...
