We introduce a new structured channel impulse response (CIR) estimation method for sparse multipath channels where we demonstrate a robust way of restoring the pulse shape into the composite CIR. We call this novel CIR estimation method time-of-arrival based blended least squares (TOA-BLS) which uses symbol rate sampled signals, and it is based on ...

In this paper we introduce a new structured channel impulse response (CIR) estimation method for sparse multipath channels. We call this novel CIR estimation method Time-Of-Arrival based Blended Least Squares (TOA-BLS) which uses symbol rate sampled signals, based on blending the least squares based channel estimation and the correlation and cleaning

Channel estimation is vital for implementing schemes such as coherent detection and adaptive bit loading, which make OFDM an attractive PHY layer technology for vehicular wireless communications. However, knowledge of the exact time of arrival (TOA) information of the multi-path components of the vehicular wireless channel is required to achieve ...

On the impact of time-of-departure knowledge on the accuracy of time-of-arrival localization
Comput. Networks, 2020We analyze the accuracy of source localization methods based on time-of-arrival (ToA) measurements from a set of cooperating receivers (anchors). We consider three different system scenarios, with and without knowledge of the time-of-departure (ToD) at ...

Optimal Sensor Placement for 3-D Time-of-Arrival Target Localization
IEEE Transactions on Signal Processing, 2019This paper focuses on finding the optimal sensor placement strategies for circular time-of-arrival (TOA) localization in the three-dimensional (3D) space. The A-optimality criterion, minimizing the trace of the inverse Fisher information matrix (FIM), is
