Application of Residue Arithmetic in Communication and Signal Processing

摘要: Residue Number System (RNS) is a non-weighted number system. In RNS, the arithmetic operations are split into smaller parallel which independent of each other. There no carry propagation between these operations. Hence devices operating in this principle inherit property high speed and low power consumption. But makes overflow detection very difficult. moduli set chosen such that there generated. thesis, use residue system portrayed designing solution to various applications Communication Signal Processing. RNS finds its application where integer authoritative process, since operates efficiently on integers. New selection magnitude comparison routine sign methods were limed onset dissertation. A good example digital image. The pixels represented by 8 bit unsigned number. Thus primarily restricted small range. Hereby, novel image encryption technique depicted. results show robustness timeliness technique. This technique further compared some industry standard encryption algorithms for analysis based robustness, time other paradigms. Filters signal conditioners. Each filter functions accepting an input signal, blocking pre-specified frequency components, passing original minus those components output. A lowpass allows only low frequency signals (below specified cutoff) through output, so it can be used eliminate frequencies. design approach pass was also proposed. Some trite techniques as well as approaches adopted solve challenges. mapping data another space providing liberty work with floating numbers precision adopted. PN sequence generator formulated. algorithm generates pseudo-noise evince spread spectrum multiuser communication techniques like Gold Kasami generators.
