Low complexity resource efficient OFDM transceiver design

The resource requirements of every new generation of wireless systems solution have been far exceeding the existing system solution offerings and capabilities. The classical system solutions based on micro-controller (μC), digital signal processor (DSP) and hardwired logic combination are rigid, unscalable, inefficient and do not provide a cost effective migration path. The earlier generations of wireless systems solution were incapable of providing the scalability, configurability and expandability to adapt to the new requirements resulting in reinventing of the new design solution, and in process, learning from one generation to the next was completely abandoned. A refinement in the design methodology of the wireless systems development is needed, which takes a methodical approach towards the reusability, scalability, configurability and flexibility for the wireless systems solution. This paper proposes a novel design architecture suited for efficient wireless specific wavefront processing. The technique is developed using the top down design methodology applying the object oriented design principles while looking into the application specific solution for a certain class of wireless waveforms and functionalities. This architecture is based on systolic, localized and the distributed processing characteristics of wireless signal processing.
