The Way of Selection Antenna in Distributed Wireless Communication System

Distributed Wireless Communication System(DWCS) is a new communication system, which adapts to the future communication. In this system, antenna selection scheme plays a significant role in the communication quality which will influence the communication system performances. In this paper, the antenna selection method of DWCS is presented, and then makes detailed theoretical analysis. By selecting the number of antenna and dynamic formation of virtual cells, and then performance analysis results are in good agreement with simulation results, which verifies the validity of the method. The simulation shows that the antenna selection method of DWCS with dynamic virtual cells is better than the antenna selection method without dynamic virtual cells.

Capacity Analysis and Simulations of Distributed Wireless Communication System

The information theoretic capacity of a single user distributed wireless communication system (DWCS) is investigated and compared to that of traditional cellular MIMO system. Simulation results show that, DWCS always outperforms traditional MIMO system, and the capacity gain increase with the incremental number of the fixed antennas. Moreover, the use of distributed antennas in DWCS can average the shadowing effect and solve the near-far problem efficiently.
