Clock and Orientation-Robust Simultaneous Radio Localization and Mapping at Millimeter Wave Bands
This paper proposes a radio simultaneous location and mapping (radio-SLAM)
scheme based on sparse multipath channel estimation. By leveraging sparse
channel estimation schemes at millimeter wave bands, namely high resolution
estimates of the multipath angle of arrival (AoA), time difference of arrival
(TDoA), and angle of departure (AoD), we develop a radio-SLAM algorithm that
operates without any requirements of clock synchronization, receiver
orientation knowledge, multiple anchor points, or two-way protocols. Thanks to
the AoD information obtained via compressed sensing (CS) of the channel, the
proposed scheme can estimate the receiver clock offset and orientation from a
single anchor transmission, achieving sub-meter accuracy in a realistic typical
channel simulation.Comment: This is the author's pre-print version of a paper accepted for
