论文摘要
本文提出了基于稀疏多径通道估计的无线电同时位置和映射（无线电 - SLAM）方案。通过利用毫米波带的稀疏通道估计方案，即对到达角度（AOA）的多个到达角度（AOA），到达的时间差（TDOA）和出发角度（AOD）的高分辨率估计值，我们开发了无线电 - 链接算法，该算法在不需要时钟同步，接收者方向知识，多个锚点的情况下运行，而无需任何要求。得益于通过通道的压缩传感（CS）获得的AOD信息，提出的方案可以估计接收器时钟的偏移和从单个锚传输的方向，从而在现实的典型通道模拟中实现了子计的精度。
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.
