| Outline of Final Research Achievements |
In the next generation of wireless communication, high speed (bits/sec), low transmission latency (msec) and high density of simultaneous users (users/square km) are requested. In order to fulfil those needs, the wider transmission bandwidth than today is required and it leads to the utilization of high frequency band like millimeter wave. However, as the high frequency waves like millimeter meter waves suffer from high propagation loss, the sharp beam forming of transmit antenna has to be done. In order to achieve this beam forming with very reliable transmission, massive MIMO technique which uses very large number of transmit antenna elements, space time coding technique for transmit signals emitted from antenna elements and relaying technique which amplifies the transmission signal and enlarges the coverage area are all needed. This research combined those techniques and realized very reliable high speed wireless communication. Also MIMO FSK with constant envelope was studied.
