The Direct Form FIR channel is utilized for DSP application where the channel request is settled. For the most part this channel devours more range and power. To defeat this issue Multiplier Control Signal Decision window (MCSD) plans is joined into Direct Form FIR channel to powerfully change the channel arrange. MCSD structures comprise of Control flag Generator (CG) and Amplitude Detection (...

Finite Impulse Response (FIR) digital filters have potential for high-speed and low-power realization through parallel processing on FPGA. In this paper, an efficient implementation of FIR filters, which uses a Booth Radix-8 multiplier, is suggested. For implementation of the said FIR filter MATLAB FDATool is employed to determine various filter coefficients. The 8 order FIR filters have been d...

The Finite Impulse Response (FIR) filters are widely used in many Digital Signal Processing (DSP) applications. For these applications, the low power, less area, high speed and low complexity FIR filter architectures are required. The researchers have proposed many FIR filters to meet the above design specifications. This paper is focused on the some efficient reconfigurable FIR filter architec...

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...

Finite-impulse response (FIR) Filter is widely used in wireless sensor networks as a signal pre-processing step. Because sensor nodes require a long working periods and ultra-low cost, traditional FIR structures are inapplicable as multipliers occupy too much die size for such node’s chips. This paper proposes novel FIR filter structures used in the design of application specific integrated cir...

We report the generation of pulsed optically pumped far-infrared (FIR) radiation with a repetition rate of 200 kHz. These pulses were obtained in a straightforward method by pumping a FIR resonator with a high repetition rate, rf-excited, waveguide CO2 laser. Pulses approximately 50 ns wide were generated both at 432.6 m in HCOOH, and 117.7 +n in CH,F,. The pulse width of the FIR radiation was ...

Digital finite impulse response (FIR) filters play a very important role in digital signal processing (DSP) applications ranging from image and video processing to wireless communication. Digital FIR filter is primarily composed of multipliers, adders and delay elements. Several techniques have been reported in the open literature to implement digital FIR filters using Field Programmable Gate A...

Transmitter induced redundancy using FIR filterbanks can be used to equalize FIR channels irrespective of channel zeros and facilitate blind channel estimation. At the receiver end, linear or non-linear (DFE) FIR filterbanks can be applied to recover the transmitted data. Closed form expressions are derived for the FIR linear or DFE filterbank receivers. By applying blind channel estimation met...
