| Research Abstract |
In the study, we have proposed high-efficient radio packet access techniques including multi-access schemes, radio resource assignments, multiplexing schemes of control signals, high-order MIMO channel techniques, relay/multi-hop techniques, and investigated the effects of these techniques for fourth generation mobile communications, which is called International Mobile Telecommunications (IMT)-Advanced.
