In wireless channel the noise has a zero mean. This channel property can be used in the enhancement of the noise performance in the digital receivers by oversampling the received signal and calculating the decision variable based on the time average of more than one sample of the received signal. The averaging process will reduce the effect of the noise in the decision variable that will approa...

This article provides the author's perspective on the development of digital hearing aids and how digital signal processing approaches have led to changes in hearing aid design. Major landmarks in the evolution of digital technology are identified, and their impact on the development of digital hearing aids is discussed.

he wide-spread and growing use of portable, battery-powered devices like cellular telephones, audio-capable personal digital assistants (PDAs), MP3 players and similar applications has resulted in an increasing demand for miniature, ultra low-power digital signal processing (DSP) technology. Many of these devices make heavy use of digital signal processing techniques like modulation, demodulati...

This paper reviews digital signal processing techniques that compensate, mitigate, and exploit fiber nonlinearities in coherent optical fiber transmission systems.

The problem of high resolution radiometry imaging is considered. An iterative method of radiometry image processing is presented in the paper. The problem of image reconstruction is considered as the inverse ill-posed problem. The method proposed makes use of the iterative technique and regularization procedure to improve image quality. Nonlinearity of the method is provided by a nonnegative co...

Bargaining with reading habit is no need. Reading is not kind of something sold that you can take or not. It is a thing that will change your life to life better. It is the thing that will give you many things around the world and this universe, in the real world and here after. As what will be given by this digital signal processing in communications systems, how can you bargain with the thing...

The Arduino microprocessor platform would seem to be an unlikely choice for teaching labs in Digital Signal Processing (DSP), however, from an educational perspective it can work very well, particularly in a 10-week introductory course. The Arduino platform is easy to get started with. It allows more time to be spent on teaching the fundamentals of DSP, and less on learning the integrated devel...
