Outline of Final Research Achievements

In this study, we proposed high-efficiency radio packet access techniques and investigated the effects of the proposed techniques in heterogeneous networks for future mobile communications. More specifically, we proposed the techniques including non-orthogonal physical channel multiplexing using Faster-than-Nyquist (FTN) considering control signaling overheads, multiplexing scheme and accurate channel estimation method for control signals, Multiple-Input Multiple-Output (MIMO) multiplexing scheme using adaptive modulation and coding, and fast cell search method in heterogeneous networks. We showed the effects of these techniques by link-level and system-level simulations.
