Abstract :
Analyzing the indoor/outdoor multipath propagation structure is an important process in developing anti-fading techniques for high speed digital radio communication. The multipath propagation structure can be clarified by estimating the direction of arrival (DOA), time of arrival (TOA) and relative power of the incident waves. An algorithm for TOA/DOA estimation is proposed to clarify the indoor/outdoor multipath propagation structure, and its validity is demonstrated by computer simulation. The algorithm features a low calculation load because of the small size covariance matrix to be handled and the applicability under the condition where the transmitter or receiver is moving since no reference cable is needed between the transmitter and receiver.
