Abstract:

Coherent schemes with accurate channel state information are considered to be important to realizing many benefits from massive multiple-input multiple-output (massive MIMO) cellular systems involving large antenna arrays at the base station. In this talk we introduce and describe noncoherent communication schemes, i.e., schemes which do not use any instantaneous channel state information, and find that they have the same scaling behavior of achievable rates as coherent schemes with the number of antennas. This holds true not only for Rayleigh fading, but also for ray tracing models. Analog signal processing architectures for large antenna arrays based on our analyses will be described. We also consider wideband large antenna systems and identify a bandwidth limited regime where having channel state information does not increase scaling laws, and outside of which there is a clear rate penalty. This talk is based on joint work with Alexandros Manolakos, Andrea Goldsmith, Felipe Gomez-Cuba, and Elza Erkip.



Biography:

Mainak Chowdhury is a Ph.D. candidate in the Wireless Systems Laboratory at Stanford University. He received a Bachelor of Technology in Electrical Engineering from the Indian Institute of Technology, Kanpur, India (2011), and a Master of Science in Electrical Engineering from Stanford University (2013). His research focuses on communication systems with a large number of transmitters or receivers.
