| Outline of Final Research Achievements |
The recent mobile communication schemes such as smart phones, wireless LAN’s and mobile WiMax’s are now gradually improving their high data rates and reliability. However, due to the rapidly increasing user traffics, the high data rates and reliability should further be improved. Furthermore, as those schemes are based on the retransmission strategy to ensure the high reliability, they lack in the real time property. Accordingly, this research aimed to develop the high speed wireless transmission schemes without retransmission but with very high reliability. Through the advancement of various element technologies in space time coded MIMO techniques, we developed the new schemes to achieve the objective. Especially, we developed the downlink MIMO MU techniques, relaying schemes, single carrier receiver with iterative equalization and MFSK coherent receiver techniques.
