This letter proposes a dual shift invariant TOA estimation method for multi-band signals. Although conventional shift invariant TOA estimation methods have been proposed to exploit a single shift invariant structure of the transformed signals, the proposed method is developed to make use of the dual shift invariant structure of the transformed multi-band signals. The performance of the proposed method is compared with that of the Cramer-Rao lower bound (CRLB) and conventional algorithms such as MUSIC, matrix pencil, TLS-ESPRIT in additive white Gaussian noise (AWGN) and multipath channel.
