“…Reconfigurability and low complexity are the two key requirements of the SDR channelizers. Architecture for implementing low complexity and reconfigurable finite impulse response (FIR) filters for channelizers is proposed in paper [25]. Research paper [26][27] introduced the rate distortion optimized resource allocation for video transmission over IIR wireless direct-sequence code-division multipleaccess (DSCDMA) channels.…”

Infinite impulse response (IIR) filter designs mainly aims on either low area-cost or high speed or reduced power consumption. Infinite Impulse Response filters are the most important element in signal processing and communication. IIR filters can achieve filtering characteristic using less memory and calculations than a similar FIR filter. Multipliers are the basic building block in DSP, microprocessors and other applications. The system's performance is entirely dependent upon the multipliers beca have large area, long latency and consume considerable power hence there is a need to design high speed, low power consumption, regular and less area multipliers. The speed of the multipliers can be increased by reducing the number of partial prod Parallel multipliers are fastest among all multipliers. Booth multipliers are the parallel multipliers that operate on signed operands in two's complement form and have high performance, low power consumption and does not suffer from bad regularity. presents an efficient implementation of high speed parallel multiplier using Radix-4 which further used in the designing of IIR filter. Pre implemented to increase the lifespan of electronic components and increase reliability of the voltage system. Pre-charge is intended to minimize propagation delay time. Pre-charge of the power line voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. In other systems su as vehicle applications, pre-charge will occur with each use of the system, multiple times per day.

“…On the other hand, they required more hardware. Research paper [16] develops a multirate digital filter design for the vestigial side band (VSB) modulator required in the analog TV transmission systems, like PAL. The main benefit of it is that the resulting design has significantly lower complexity than in the earlier designs using FIR filters and it is quite feasible for implementation as an ASIC or even on an FPGA circuit.…”

In this paper, we have reviewed a brief description of the ways in which the multi-rate filters are implemented in various fields of digital communication system during last decade. The main objectives of this survey paper is to find the application of multi-rate digital filters used in various fields, such as; speech coding, scrambling, adaptive signal processing, image processing, software defined radio, audio and video processing etc. In most applications multi-rate systems are used to improve the performance, or for enlarged computational efficiency. The multi-rate digital filters are simpler faster and economic as compare to previously reported general filters. Today's enhancement of wireless communication is based on the integration of various application, needs more and more data rate, which is restricted by various impairments. Multi-rate system has solution for the above problem of wireless communication. We, hope that this paper will help both academic as well as industry research by providing the different application of mult-rate filters at one place.

“…The best structures for implementing decimation and interpolation filters in cases where the phase linearity is not important, are the so-called recursive Nth-band filters Saramäki & Renfors, 1998;Yli-Kaakinen et al, 1999). 1 These recursive Nthband filters when used alone for decimation by the factor of N suffer, due to their properties, from the drawback that, after specifying the passband edge to be ω p = απ/N with α < 1, only aliasing into the passband region [0, ω p ] can be fully avoided, but aliasing into the transition band [ω p , π/N] occurs.…”
