Multirate System for Different DNRs

Study of different genetic properties in a DNA or RNA sequences requires converting base sequence into numerical sequence through genomic signal processing (GSP) techniques. It is noteworthy to mention that genomic signal is digital in a very real sense, as it can be represented in the form of sequences of finite number of entities. In particular, DNA and proteins can be represented by character strings. In this paper, multi-rate filter has been used and different numerical mapping schemes of a DNA sequence has been taken as input of the filter. At the same time, designing of a different mapping scheme filter have been done when we are decimating the input signal.

I. Introduction

The 21st century is believed to be known as an era of many scientific and technological ventures based on the processing and interpretation of Genomic data. Digital signal processing is the key enabling technology for modern genomic signal Processing .GSP allows using signal processing theory, algorithms and mathematical methods of digital signal processing. GSP methods are required for transformation or mapping of genomic information or sequences into a numerical representation. In recent years the use of DSP, the subject of genomic sequence analysis has gotten a lot of attention, and it's given us a fresh perspective on a lot of difficulties, including Prediction of exons in DNA sequences.
