| Research Abstract |
A multiple access scheme that achieves high bit rate transmission and shares limited frequency resource by multiple users quite efficiently has been investigated for future mobile communication systems. From the viewpoint of information theory, the study mainly focused on interleave division multiple access (IDMA) that separates the users by exploiting both low-rate channel code and individual interleaver. For the wider bandwidth, IDMA is combined with OFDM, and the study performed establishment of highly efficient transmission technique, optimization of transmitter and receiver structures, and clarification of system requirements. The research has almost achieved the original goals.
