A 3-D spatiotemporal prediction-error filter (PEF), is used to enhance foreground/background contrast in (real and simulated) sensor image sequences. Relative velocity is utilized to extract point-targets that would otherwise be indistinguishable on spatial frequency alone. An optical-flow field is generated using local estimates of the 3-D autocorrelation function via the application of the fa...

In this paper we proposed a novel enhanced gate diffusion (EGDI) adder is designed and implemented in Distributed Arithmetic (DA) based Finite Impulse Response (FIR) filter. Generally multipliers, adders shift accumulators are the basic blocks present FIR filters. The hardware architecture of multipliers very high. To get rid this, multiplier less needed So place key role filters which will occ...

Abstract This paper presents an improved design of reconfigurable infinite impulse response (IIR) filter that can be widely used in real-time applications. The proposed IIR is realized by parallel–pipeline-based finite (FIR) filter. FIR filters have excellent characteristics such as high stability, linear phase and fewer precision errors. Hence, FIR-based more attractive selective signal proces...

This paper is concerned with the design and implementation of frequencyselective recursive filters in which the filtered output is incorporated on the input side, at various lags, via a series of feedback terms. Such devices are commonly described as infinite impulse response (IIR) filters. Filters that are devoid of feedback are apt to be described as finite impulse response (FIR) filters. Rel...

A new method for designing uniform and nonuniform digital filter banks with a specified composite response is presented. The composite response of the filter bank can be met either exactly or to within a given tolerance. We focus on filter banks in which the individual filters are finite impulse response (FIR) digital filters of possibly nonequal length, although the new method is applicable ev...

A novel approach to real-time is presented, using signal processing. algorithm Wiener filtering finite-impulse-response (FI...

Broadband wireless channels, where high data rates are transmitted, are extremely dispersive in nature. A fundamental challenge in the design of equalizers for the broadband case lies in reducing complexity. Broadband finite impulse response (FIR) beamformers employ a space-time antenna array which reduces the multipath delay spread to narrowband levels. The beamformers should additionally pres...

Transpose form finite-impulse response (FIR) filters are inherently pipelined and support multiple constant multiplications (MCM) technique that results in significant saving of computation. However, transpose form configuration does not directly support the block processing unlike direct form configuration. In this paper, we explore the possibility of realization of block FIR filter in transpo...

With the rapid development of computers and communications, more and more chips are required to have small size, low-power and high performance. Digital filter is one of the basic building blocks used for implementation in Very Large Scale Integration (VLSI) of mixed-signal circuits. This paper presents a design of decimation filter used for digital filtering. It consists of Cascode Integrated ...
