Channel model is the fundamental issue to study and design millimeter wave communications, especially for beam-tracking evaluation where large-scale antenna array is applied. In this paper, a new channel model based on 3GPP spatial channel model (SCM) framework is proposed, which introduces variant arrival and departure angles. A linear variation with time is modeled to describe the angle changes...
To obtain the receive diversity of timing acquisition, the cooperative processing of multiple distributed received antennas is considered in this paper. In the flat Rayleigh channels, we assume two remote antennas at the base station for receiving the signal transmitted from the mobile station with a single antenna. By utilizing the coverage range of each remote antenna, a constraint is exploited...
Two transmit antennas placed symmetrically for a linear cell downlink distributed antenna system with Alamouti space-time block coding over Rayleigh fading channels. For mobile station located in different places in the cell, which mode should be selected by base station from one transmit antenna or two transmit antennas? Aiming to solve this problem, a transmit mode selection scheme is developed...
