Device-to-device (D2D) communication as an underlay to cellular networks can bring significant benefits to users' throughput. However, as D2D user equipments (UEs) can cause interference to cellular UEs, the scheduling and allocation of channel resources and power to D2D communication need elaborate coordination. In this paper, we propose a joint scheduling and resource allocation scheme to improve...
In this letter, we address the optimal source and relay matrices design for the multiple-input multiple-output (MIMO) relaying broadcast channels (BC) with direct links (DLs) based on weighted sum-rate criterion. This problem is nonlinear nonconvex and its optimal solution remains open. To develop an efficient way to solve this problem, we first set up an equivalent problem, and solve it by decoupling...
In this paper, a joint thinned array and weighting design method to reduce array radiation pattern sidelobe level based L1 norm constraint is proposed. Considering that the radiation pattern of thinned array is sensitive to weighting, we joint design the thinned array and its weighting. The proposed method exploits the feature of L1 norm constraint, and attains a better array radiation pattern than...
This work presents our analysis on adaptive beamforming and combining techniques applied to a system consisting of distributed antenna arrays. Our analysis reveals the connection between the theoretical and the practical schemes for data combination. The important roles played by the canonical correlations (CC), which may or may not exist among multiple data sets in a distributed antenna system, are...
