Abstract: Digital Signal Processing is the mathematical handling of an information signal to modify or improve it. Digital Signal Processors are microprocessors specially designed to handle Digital Signal Processing tasks. These devices have seen tremendous growth in the last decade, finding use in everything from cellular telephones to advanced scientific instruments. In fact, hardware engineers use “DSP” to mean Digital Signal Processor, just as algorithm developers use “DSP” to mean Digital Signal Processing. DSP has become a key component in many consumers, communications, medical, and industrial products. This paper illustrated the role of Digital Signal Processors (DSP) for fourth generation mobile systems. The currently deployed wireless infrastructure supports the fourth generation of these standards is nearly impossible with respect to the cellular base station. Many solutions for base station or mobile station have been implemented over the years, and each solution required a combination of two components, ASICs (Application Specific Integrated Circuits), and DSPs (Digital Signal Processors). This two-chip solution partitions the processing tasks between the ASIC and DSP, respectively. Although this solution is functionally acceptable, its system cost and flexibility are not completely optimized. Global objectives and attributes that include worldwide roaming, universal connectivity, high data transmission rates, location service capability ,and support for high-quality multimedia services are now required.
