Searching for Optimal Spread Spectrum Technique and 5G Massive Machine Type Communications -New Approach of Almost Periodicity (Weyl) Towards Communications

Speaker: Prof. Ken Umeno
Affiliation: Kyoto University, Kyoto Japan


What is the optimal spread spectrum communications? What is the optimal spectrum sharing method for 5G Massive Type Communications? This is the key technical issue of 5G.

Based on the past research on chaotic communications, the speaker introduced new concept: almost periodicity.  Here, the possibilities of technical aspect of almost periodic spread spectrum communications are assessed together with the study of Searching for optimal asynchronous CDMA communications and our approach towards 5G Massive Machine Type Communications.


Ken Umeno is a Professor at the department of Applied Mathematics and Physics, Graduate School of Informatics, Kyoto University, Kyoto, Japan since April 2012.  He found superefficient Monte Carlo computation by using chaotic dynamics in 2000 (KU, JJAP 2000) and recently introduced applications of spread spectrum correlation analysis to detect  ionosphere pre-seismic anomalies based on GNSS  (Global Navigation Satellite Systems) big data analysis-(Iwata-Umeno, JGR 2016 and 2017).
