An Approximate Solution for Symbol-Level Multiuser Precoding Using Support Recovery
Alireza Haqiqatnejad, Farbod Kayhan, Bjorn Ottersten
In this paper, we propose a low-complexity method to approximately solve the SINR-constrained optimization problem of symbol-level precoding (SLP). First, assuming a generic modula…
Robust SINR-Constrained Symbol-Level Multiuser Precoding with Imperfect Channel Knowledge
Alireza Haqiqatnejad, Farbod Kayhan, Bjorn Ottersten
In this paper, we address robust design of symbol-level precoding for the downlink of multiuser multiple-input multiple-output wireless channels, in the presence of imperfect chann…
Power Minimizer Symbol-Level Precoding: A Closed-Form Sub-Optimal Solution
A. Haqiqatnejad, F. Kayhan, B. Ottersten
In this letter, we study the optimal solution of the multiuser symbol-level precoding (SLP) for minimization of the total transmit power under given signal-to-interference-plus-noi…
Robust Design of Power Minimizing Symbol-Level Precoder under Channel Uncertainty
Alireza Haqiqatnejad, Farbod Kayhan, Bjorn Ottersten
In this paper, we investigate the downlink transmission of a multiuser multiple-input single-output (MISO) channel under a symbol-level precoding (SLP) scheme, having imperfect cha…
Symbol-Level Precoding Design Based on Distance Preserving Constructive Interference Regions
Alireza Haqiqatnejad, Farbod Kayhan, Bjorn Ottersten
In this paper, we investigate the symbol-level precoding (SLP) design problem in the downlink of a multiuser multiple-input single-output (MISO) channel. We consider generic conste…
