Adaptation of DSP Processors for 3G and 4G Wireless Communication

Vinni Sharma, Tanuja Kashyap

Technological advancements have resulted in significant changes in the processor architecture of mobile phones, transforming the typical mobile phones of 1990’s to modern smart phones. The next generation of mobile computing requirements will increase due to higher data rates, increased complexity algorithms, and greater computation diversity but the power requirements will be just as stringent to ensure reasonable battery lifetimes.The design of the next generation of mobile platforms must address three critical challenges: efficiency, programmability, and adaptivity. This paper presents analysis of mobile signal processing applications and advanced signal processing architectures to deal with the rigorous requirements. This paper illustrates the role of Digital Signal Processors for Third generation (3G) mobile systems and DSP architectures for 4G wireless communication.
