The secrecy outage performance of multiuser multiple-input–multiple-output (MU-MIMO) transmit antenna selection systems is analysed, where some of the users overhear transmissions as long as they are not scheduled currently. A general closed-form expression of secrecy outage probability is derived by ordering the qualities of paths and calculating the joint probability density functions. Numerical...
The inter-cell interference of orthogonal frequency division multiple access (OFDMA) based multi-cell distributed network architecture is analyzed. Based on generalized distributed cellular architecture-group cell, the interference condition without power control and with power control is analyzed respectively, and the system outage probability compared to traditional cellular structure is evaluated...
The outage probability expression of G-VMIMO system is deduced in this paper, theoretically. Numerical results of the outage probability are also obtained by computer simulation. The conclusion is derived from simulation results that the number of the DEVs contained by GT is limited, and the concrete number depends on the practical environment
This paper provides a novel cellular structure: generalized distributed cellular architecture-group cell, which is suitable for advanced physical techniques and solves the problem of smaller cells caused by higher carrier frequency used in future. The concept and the structure of the group cell are described and the slide handover strategy based on the group cell is introduced in details. The system...
