Abstract

The present paper proposes a method for simultaneously estimating the direction of arrival (DOA) and delay of multipath signals through the virtual array reception of broadband signals. In order to confirm the principles behind the proposed method, a broadband signal of 42MHz, equivalent to seven adjacent TV channels being transmitted from the Tokyo Skytree, was acquired and stored in a personal computer as the reception signal, which acts as reference signal. In addition, a multipath signal with DOA and delay was generated using a personal computer. Signal processing revealed that DOA and delay could be identified correctly. Finally, a multipath propagation analysis is conducted for an actual outdoor propagation environment as a demonstration of the proposed method.
