We choose commodity PC as the underlying platform. There are many ways of building high-performance software radios. This is a significant challenge for any software radio. The implementation platform must then be able to handle OFDM, 64QAM, MIMO, CSMA, 40MHz channel width, and tens to hundreds Mbps data rate. In late 2000s and early 2010s, the state-of-the-art is Wi-Fi and LTE.
The goal of Sora is to develop the most advanced software radio that is capable of implementing the state-of-the-art wireless communication technology easily and efficiently. The Microsoft Research Software Radio (Sora) is one such recent success in advancing the state of the art in software radio technology.
Over the years, researchers and engineers have made remarkable progress and have been constantly pushing the hardware-software boundary. Software radio (or software-defined radio, SDR) is an engineering pursue in wireless communication technology field that one day all wireless signal processing functions, which are typically implemented in hardware today, will be done completely in software.
