the main purpose of this paper is to introduce afast method for gene prediction in dna sequences based on the period-3 property in exons. first, the symbolic dna sequences are converted to digital signal using the eiip method. then, to reduce the effect of background noise in the period-3 spectrum, we use the discrete wavelet transform (dwt) at three levels and apply it on the input digital sig...

This paper investigates digital data hiding schemes. The concept of information hiding will be explained at first, and its traits, requirements, and applications will be described subsequently. In order to design a digital data hiding system, one should first become familiar with the concepts and criteria of information hiding. Having knowledge about the host signal, which may be audio, image, ...

This paper describes a GPSNavigation Set specifically designed for commercial aviation applications. The designphilosophyfor thi~ set hasbeento minimizeRF signal processing in favor. of digital signal processing and to minimize hardware digital signal processing in favor of software digital signal processing. This philosophy has resulted in a unique architecture. This architecture is described ...

In this paper, a new digital intermediate frequency modulator for conventional TV signals using digital signal processing is presented. A composite colour video signal and two associated audio signals are converted into a digital composite TV signal with spectrum at intermediate frequency. The modulator is designed for the high quality requirements that exist in professional equipment for CATV ...

The paper summarizes the FMT modulation prototype filter design and its efficient implementation on DSP. The optimum design of algorithms for digital signal processors with VLIW architecture is described. Using this new approach it was, for example, possible to optimize compilation from the C language into the assembler of TMS320C6414 digital signal processor for implementation of FMT modulatio...
