TDOA estimation method using 60 GHz OFDM spectrum

60 GHz Blockage Study Using Phased Arrays

The millimeter wave (mmWave) frequencies offer the potential for enormous capacity wireless links. However, designing robust communication systems at these frequencies requires that we understand the channel dynamics over both time and space: mmWave signals are extremely vulnerable to blocking and the channel can thus rapidly appear and disappear with small movement of obstacles and reflectors....

A robust TDOA estimation method for in-car-noise environments

Time difference of arrival (TDOA) estimation is one of the key techniques in array signal processing and has wide applications in hands-free speech interface. TDOA is used to derive the time difference of signal propagation from source to the spatially separated microphones. The acoustic transfer functions ratio (ATF-s ratio) method is one of the robust approaches to get TDOA estimate in presen...

A Novel Position Estimation Method Using Hybrid TOA and TDOA in AIS

Abstract Nowadays, robust position, navigation and timing (PNT) information becomes an necessary foundation of e-navigation and requires the trials and development of a new system to improve marine navigation. Positioning estimation methods and their implementation are being investigated in the literature due to their importance in safety and national security services. In this paper, we propos...
