Precoder design in user-centric virtual cell networks. Shi, J., Chen, M., Zhang, W., Yang, Z., & Xu, H. In 2017 25th European Signal Processing Conference (EUSIPCO), pages 1055-1059, Aug, 2017. Paper doi abstract bibtex We consider the coordinated transmission in the downlink of user-centric virtual cell networks where a number of Remote Radio Heads (RRHs) form a virtual cell to serve every user equipment (UE). We introduce two cell formation schemes and design the precoders in order to optimize the sum data rate with fairness among users. The original non-convex weighted sum-rate maximization problem is converted into an equivalent matrix-weighted sum-mean square error (MSE) minimization problem, which is solved by a distributed precoding algorithm. Simulation results show that the proposed weighted minimum mean square error (WMMSE) algorithm provides a substantial gain over existing algorithms in terms of sum data rates with moderate implementation cost.
