Digital Signal Processing Applied in Mobile Communications

Digital Signal Processing is an important software tool for several functions over digital signal, and Digital Signal Processors are microprocessors and microcontrollers specifically manufactured for the digital signal processing tasks. These DSP chips are used in everything from mobile phones to advanced scientific equipment including medical instruments. ”œDSP” mean for hardware as Digital Signal Processor or chip, software developers use to mean ”œDSP” as Digital Signal Processing. DSP has become a main functional component in communications, medical and industrial products. This paper describes the role of the Digital Signal Processing DSP in mobile communications from second to fifth generation. Mobile communications in present scenario 5G advances a lot offering huge facilities like universal roaming with seamless connectivity, high data transfer rates, site service capabilities and support for high quality multimedia services worldwide by using digital signal processing technique. In all steps of a mobile communications system, application of DSP is done for carrying out effective work. It is observed that digital signal processing becomes back bone to mobile communications from second to fifth generation and so on.
