This paper presents a novel approach for implementing power-efficient finite-impulse response (FIR) filters that requires less power consumption than traditional FIR filter implementation in wireless embedded systems. The proposed schemes can be adopted in the direct form FIR filter and achieve a large amount of reduction in the power consumption. By using a combination of proposed methods, bal...

We experimentally characterize the performance of a continuously tunable all-optical complex-coefficient finite-impulse-response (FIR) filter that exploits nonlinear signal processing (multiplexing and multicasting) and conversion-dispersion-based optical delays. Various length (three and four) optical FIR filters with different tap amplitudes (from 0 to -9 dB), tap phases (from 0 to 2π), and t...

We propose a new way of performing stable and more efficient F − X wavefield extrapolation for the application of seismic imaging and datuming via Infinite Impulse Response (IIR) F − X filters. To prove the concept, we used model reduction techniques to design the complex-valued IIR F −X extrapolation filters. Simulation results indicate that we can obtain stable designs using the proposed filt...

Lubin Chang, Member, IEEE Naval University of Engineering, Wuhan, China (e-mail:[email protected]) Abstract—This note reveals an explicit relationship between two representative finite impulse response (FIR) filters, i.e. the newly derived and popularized Kalman-Like unbiased FIR filter (UFIR) and the receding horizon Kalman FIR filter (RHKF). It is pointed out that the only difference of the ...

Subtractive dithered quantizers are examined to minimize the signal-band dither power. The design of finite impulse response(FIR) filters that shape most of the ditherpower out of the signal band while maintaining the benefits of dithering are dealt with in detail. Simulation results for lowmedium resolution quantizers are presented to highlight the overall design consideration.

In this paper, a new digital phase-locked loop (DPLL) is proposed based on finite impulse response (FIR) filters. The proposed DPLL is more robust to incorrect noise information than the existing DPLL using fixed gain. We show the effectiveness of the proposed DPLL via a numerical example.

Pulse shaping filters have been designed and implemented by using Raised cosine filter, Nyquist filter and optimized half band filters for software defined radio (SDR) based wireless applications. In signal processing, a finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite tim...

We show that the reduced-rank output signal computed via truncated (Q)SVD is identical to that from an array of parallelly connected analysis-synthesis finite impulse response (FIR) filter pairs. The filter coefficients are determined by the (Q)SVD, and the filters provide an explicit description of the reduced-rank noise reduction algorithm in the frequency domain.

This paper presents one simple method for a design of multiplierless finite impulse response (FIR) filters by a repeated use of the same filter. The prototype filter is a cascade of a second order recursive running sum (RRS) filter and its corresponding expanded versions. As a result, no multipliers are required to implement this filter.

In this paper optimal FIR filter techniques are used to design any type of FIR filter. This techniques design the smallest-order FIR filter for a given set of specification. It is based on the concept that the filter exhibits ripples of equal length in the band-pass and band-stop. The design algorithm of these Equiripple FIR filter uses iterative polynomial interpolation. Input signal has a gre...
