Fundamental Study on Indoor Intrusion/Location Detection using Radio Propagation Change

KUROSAKI Yuta, TANAKA Kei, YAMADA Hiroyoshi, YAMAGUCHI Yoshio

IEICE technical report AP2010-42 ( 7 ) 25 - 30 2010.7

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In recent years, several indoor intrusion/event detection methods using radio propagation change caused by intruder have been proposed. One of the indoor intrusion/event detection methods with an array antenna can detect intrusion/event using receiving signal eigenvector change. In addition, the method intrusion/event detection method using MIMO channel change also has been proposed. However, these reports have not discussed intruder location detection. In this report, we consider possibility of indoor intrusion/location detection by the computer simulations.

Data Symbol Reduction for Blind MIMO Transmission by using ICA

SUGAI Kohei, YAMADA Hiroyoshi, NISHIMORI Kentaro, YAMAGUCHI Yoshio

IEICE technical report AP2010-38 ( 7 ) 1 - 6 2010.7

Language：Japanese Publisher：The Institute of Electronics, Information and Communication Engineers

In the MIMO system, transmitted streams are multiplexed spatially at the same frequency. This causes inter-stream interference at the receiver. Therefore, equalization/decoding method is necessary. Least Squares Channel Estimation (LSCE) is often used as the method. However, overhead of throughput due to training symbols is a problem for effective transmission. In this report, we employ on Independent Component Analysis (ICA) as a blind method without the training symbols. We have reported effectiveness of the ICA with a small number of training symbols compared with that of the LSCE. However, since the ICA is statistical channel estimation method, many data symbols are often needed. In this report, we propose to apply a pre-filtering processing to the transmitting signals to obtain better performance compared with the conventional ICA. Computer simulation results are shown to demonstrate availability of the method. Furthermore we provide some experimental results to show the effectiveness of proposed method in the real environment.
