In this paper, we propose a new space-time modulation scheme using quadrature amplitude modulation division for a two-user massive multiple-input multiple-output (MIMO) uplink system, in which channel state information (CSI) is unavailable at both the transmitter and the receiver. It is proved that our proposed transmission scheme enables both the large scale channel coefficients and the transmitted...
This letter considers a noncoherent two-user uplink system, where each user has a single antenna and a base station is equipped with a large number of antennas. It is assumed that small scale channel fading is Rayleigh fading and quasi-static in two consecutive time slots and changes to other values independently in the next block. For such massive MIMO uplink system, we propose an orthogonal binary...
In this paper, we consider correlated multiple-antenna communication systems having M transmitter antennas and N receiver antennas (M ≤ N) with a zero-forcing (ZF) decision-feedback (DF) detector. We assume that the full knowledge of channel state information is available at the receiver and only the first- and the second-order channel statistics are known at the transmitter. By scaling up the antenna...
