Research Abstract

In the study, we proposed basic techniques for efficient multi-access schemes including orthogonal frequency division multiple access (OFDMA) and single-carrier FDMA, radio resource assignment control method, efficient multiplexing of control signals, accurate channel estimation method and MIMO channel techniques, and investigated the effects of these techniques aiming at the application to the cellular systems beyond International Mobile Telecommunications (IMT)-Advanced with the peak data rate of greater than 1 Giga bits per second.
