Research Abstract |
This study focuses on MIMO-OFDM wireless communications in which MIMO spatially multiplexes signals by multiple transmit and receive antennas, and OFDM stands for orthogonal frequency division multiplexing to maintain good transmission performance even under multipath conditions. For the MIMO-OFDM wireless communication, we have developed random access techniques that can improve spectrum efficiency by channel assignment with multiuser detection (MUD). Especially, (1) interleave division multiplexing to assign different interleavers to individual signals, (2) packet retransmission schemes that separate packets multiplexed in the same time and frequencychannel by MUD and then combine retransmitted packets, and so on have been investigated.
