Abstract
Due to high blockage loss of millimeter wave (mmwave) channel, researchers proposed to use multipath components (MPCs) as alternative communication links when line of sight (LOS) signal gets blocked. However, when both link ends are moving such as in Device-to-Device (D2D) scenario, MPC parameters show variation in their characteristics. In such scenarios, MPCs need to be persistent with transmitter/ receiver's movement in order to be used as a communication link. The main goal of this paper is to the characterize persistent MPCs for the mm-wave propagation channel at 30 GHz frequency in an urban environment. To this end, we develop a set of algorithms to resolve these MPCs. We investigate how persistent MPCs evolve and changes their characteristics in both temporal and angular domain with receiver's movement. We also analyze the probability of occurrence of persistent paths of different lengths and differential change of their azimuth angle of arrivals (azimuth- AOAs) throughout the movement. These information of persistent paths will help the system developer to design blockage effect immune communication links for D2D user.
