The mobile communication systems today, have different radio spectrum, radio access technologies, and protocol stacks depending on the network being utilized. This gives rise to need of a flexible hardware platform that is capable of supporting all the different standards in the entire wireless communication frequency range. We present a generic baseband prototype architecture for SDR applications, subdivided into a high level control module and a digital signal processing engine. The DSP engine is composition of highly configurable processing blocks, each dedicated to specific algorithms based on the analysis of different standards. We also present the internal architecture, simulation results and use cases for different air-interfaces of two processing blocks as case studies.
