Abstract:
Due to the rise in complexity of current and next-generation communication systems, thedevelopment cost for these systems is becoming increasingly prohibitive, especially forapplications that do not benefit from economies of scale. The existing paradigm of teamsthat focus separately on theory and algorithm design, HW/SW design, prototyping andimplementation, with a likewise diverse set of tools and HW/SW platforms, is proving tobe inefficient, especially with the ever-tightening cost and time-to-market requirements. Hence, a unified platform that simplifies transition from theory and algorithmdevelopment to first prototype implementation is highly valuable.
In this paper/talk, we explore the benefits of a highly integrated hardware and softwareplatform for the design and prototyping of a 2x2 LTE-MIMO wireless link. We investigatethe use of parameterized synchronous dataflow model of computation to specify thefunctionality, which in tandem with a computing platform consisting of traditionalprocessor, FPGA, and tightly-integrated real-world I/O, can allow the communicationsexpert to focus on the key innovative aspects of his system, and selectively abstract thelow-level details that the researcher considers distractions. We describe the benefitsof this approach, and show a working prototype of the LTE system built using thisparadigm.
