TOA estimation algorithm based on shift-invariant technique for multi-band signals

Abstract

This paper proposes a new TOA estimation algorithm based on shift invariant structure for multi-band signals. The performance of the proposed method is compared with Cramer-Rao lower bound (CRLB) and the conventional algorithms such as MUSIC, matrix pencil, TLS-ESPRIT in additive white Gaussian noise (AWGN) and multipath channel. © Springer-Verlag Berlin Heidelberg 2014.
