Research Abstract |
The shortage of frequency spectrum is serious problem. Recently, MIMO and Cognitive Radio are attracting much attention. In MIMO, the parallel transmission in single frequency channel can be constructed. In cognitive radio, the accurate recognition and adaption to wireless communication environment are available, MIMO and Cognitive radio are powerful for achieving the high efficiency of frequency usage. In MIMO, the number of transmitted signals in the channel should be specified. In this report, the technique for specifying the number of transmitted signals is considered. In the experiment of the actual equipment, the requirement of implementation for it is clarified.
