Software aided radio communication new wave in information technology

Digital signal processing refers to the electronic processing of signals. DSPs are essentially super fast number crunchiers and just about any application that involves rapid numeric processing is a candidate for digital signal processing. With the growing need for base stations, which offers an operator a way to transition towards 3rd generation technologies, base stations will adopt software defined radio technology to produce a communication platform. It will provide simultaneous radio frequency coverage. The present paper deals with the overview of the application of signal processing algorithms and communications software technology in a wireless communication system such as mobile communication in terms of (i) investment preservation (ii) scalable functionality (iii) ease of platform transition (iv) flexible system configuration.
