Design Paradigm for Standard Agnostic Channelization in Flexible Mobile Radios
Abstract
The requirement of flexibility and multimode support in emerging communication paradigms has introduced new design challenges for implementing the hardware accelerator cores, which were typically optimized for a single mode of operation. This paper focuses on the computationally intensive channelization function in a flexible radio. This work introduces a theoretical framework, to systematically identify commonalities and redundancies in the channelization specification across multiple modes. A novel sample rate conversion ratio factorization strategy is also introduced, that allows a significant portion of the channelization accelerator to be hardwired and reused across multiple modes of operation.
