Efficient 1D and circular symmetric 2D FIR filters with variable cutoff frequencies using the Farrow structure and multiplier-block
This paper proposes new structures for realizing 1D and circular symmetric 2D FIR filters with variable cutoff frequencies. They are based on the interpolation of the impulse responses using the Farrow structure. The coefficients of the sub-filters in the Farrow structure are represented in sum-of-powers-of-two (SOPOT) coefficients. which can easily be implemented as simple shifts and additions...
متن کاملContinuously Variable Bandwidth Sharp FIR Filters with Low Complexity
In software defined radio (SDR), sharp filters of different bandwidth are required to fine tune the desired channel. This requires different computational resources and large number of filter coefficients. This paper proposes a continuously variable bandwidth sharp finite impulse response (FIR) filter with low distortion and low complexity. For this, a fixed length FIR filter is used with two a...
متن کاملBinaural Noise Reduction Using Frequency-Warped FIR Filters
Binaural noise-reduction techniques based on Multichannel Wiener filters (MWF) have been reported as promising candidates to be used in binaural hearing aids because of their efficient noise reduction at any arbitrary direction of arrival of the target signal and the preservation of localization cues. The implementation of these techniques have been reported for FFT-based processing and wavelet...
متن کاملOptimization Of Frequency-Response Masking Based Fir Filters
A very efficient technique to drastically reduce the number of multipliers and adders in implementing linear-phase finite-impulse response (FIR) digital filters in applications demanding a narrow transition band is to use the frequency-response masking (FRM) approach originally introduced by Lim. The arithmetic complexity can be even further reduced using a common filter part for constructing t...
متن کاملLow-Power Implementation of Frequency Response Masking Based FIR Filters
This paper presents a design method for high-speed, lowpower, and multiplication-free arbitrary bandwidth shape FIR filter based on frequency response masking technique (FRM). It modifies the FRM structure to replace the long bandedge shaping filter with several short filters in cascaded connection. The proposed method utilizes a systematic way to factorize the long bandedge shaping filter into...
