We study an uplink scenario of single-cell multi-user massive multiple-input multiple-output (mMIMO) communication systems with a semi-orthogonal multiple-access (SOMA), where the channel state information is acquired by transmitting uplink pilot signals superimposed on uplink data signals. We analytically find the optimal resource allocation parameters; e.g., pilot and data transmit power and training...
We study an uplink multi-user massive Multiple-Input Multiple-Output (MIMO) system employing Semi-Orthogonal Multiple-Access (SOMA) scheme. Two achievable sum-rates for the SOMA scheme are presented by use of Minimum Mean-Square Error (MMSE) channel estimation and Maximum Ratio Combining (MRC) for data detection with two detection strategies; Single-User Detection (SUD) and Successive Interference...
In this paper, blind channel estimation for Orthogonal Frequency-Division Multiplexing (OFDM) systems is considered. Based on a novel idea for biasing transmitted symbols, a simple estimation method is proposed. This method, which exploits first order statistics instead of higher orders, has a very simple structure that can be considered as the optimum solution in practical applications. The interesting...
