Abstract: This paper proposes new techniques for improving the co-channel interference immunity of the event detection system which realizes indoor event detection scheme. Similar to the conventional methods the signal subspace-based approach sometimes suffers from interference in the same frequency band because the interference signals with different incident angles affect the signal subspace of the received signals at the receiving array antenna. Two types of new event detection methods are proposed to realize immunity against noise and interference in this paper. The first method proposed in this paper exploits the cyclostationarity of communication signals to distinguish the desired signal from the interference and suppresses noise and interfering signals without major hardware design changes. Another approach that improves immunity against co-channel interference is to utilize the transmission control scheme used for personal area network systems. In the proposed method of the study, carr ier sense multiple access with collision avoidance (CSMA/CA) technique is utilized to distinguish the desired signal from the other transmitted signals. As a result of the detection of the presence of signals from other stations, the proposed system can avoid the transmitted interference signals from other systems. We are also developing an evaluation equipment to confirm the effectiveness of the proposed approach. (More)
