Abstract(in English) We have proposed an interference detection method in MIMO transmission, which utilizes periodical preamble signals in a frequency domain. We assume the collision due to multiple short preamble signals. In the propose method, second antenna receives the preamble signals while first antenna transmits the preamble signal. The interference can be detected by subtracting the short preamble signal which is multiplied by the estimated channel response from the received signal after the FFT processing. Moreover, the orthogonal In this report, we evaluate the time variation characteristics of channel state information between AP antennas when the persons sit down the desk around AP. Moreover, we show the interfering power estimation results when considering the actual propagation parameter in an indoor scenario.
