Benchmarking through NextG Alliance

In July 2015, NIST kicked off the NextG Channel Model Alliance, a consortium of companies, academia, and government organizations collaborating to allow rapid development of more accurate, consistent, and predictive channel models. Since then, the Alliance has grown to well over 250 members. The focus of the Alliance modeling group has been on a methodology to benchmark algorithms that extract the MPCs from the channel measurements, building on the previous work, i.e. replacing the actual channel sounder with a system model that considers typical hardware non-idealities, such as imperfections in array patterns and frequency response. This year, five worldwide organizations are again participating in the evaluation of the proposed methodology.
