On User Pairing in NOMA Uplink
Mohammad A. Sedaghat, Ralf R. Müller
User pairing in Non-Orthogonal Multiple-Access (NOMA) uplink based on channel state information is investigated considering some predefined power allocation schemes. The base stati…
Asymptotics of Nonlinear LSE Precoders with Applications to Transmit Antenna Selection
Ali Bereyhi, Mohammad Ali Sedaghat, Ralf R. Müller
This paper studies the large-system performance of Least Square Error (LSE) precoders which~minimize~the~input-output distortion over an arbitrary support subject to a general pena…
A New Class of Nonlinear Precoders for Hardware Efficient Massive MIMO Systems
Mohammad A. Sedaghat, Ali Bereyhi, Ralf R. Müller
A general class of nonlinear Least Square Error (LSE) precoders in multi-user multiple-input multiple-output systems is analyzed using the replica method from statistical mechanics…
Asymptotic Performance Analysis of Spatially Reconfigurable Antenna Arrays
Saba Asaad, Ali Bereyhi, Mohammad Ali Sedaghat +2
A spatially reconfigurable antenna arrays consists of an antenna array of finite length and fixed geometry which is displaced within a given area. Using these reconfigurable compon…
Nonlinear Precoders for Massive MIMO Systems with General Constraints
Ali Bereyhi, Mohammad Ali Sedaghat, Saba Asaad +1
We introduce a class of nonlinear least square error precoders with a general penalty function for multiuser massive MIMO systems. The generality of the penalty function allows us…
