  Abstract

As wireless communication systems evolve, the accuracy of a wireless positioning scheme is expected to be improved, so the related researches are being actively conducted. In this paper, we consider mmWave multiple-input and single-output (MISO) broadcast channels and propose a cooperative wireless positioning scheme among adjacent users to increase the location accuracy. In this case, we assume that the adjacent users can exactly know their relative positions and share the related information. Under these assumptions, in our proposed scheme, the adjacent users cooperatively find their centroid, and each user obtain its own position from the centroid. We analyze the accuracy of our proposed scheme via Cramer-Rao lower bound (CRLB), which is a theoretical lower bound for estimation error. Then, we compare our proposed scheme with a conventional scheme, where each user independently estimates its own position.
