  Abstract

Transmission performance of users near the cell boundary can be improved with the use of multiple radio units (RU) in a distributed antenna system. RUs equipped with a large number of antennas can provide users desired transmission performance without utilizing all of their antennas, reducing processing complexity and power consumption as well. In this paper, we analyze the performance of joint zero-forcing (ZF) beamforming with partial use of transmit antennas in terms of the average transmission capacity. We also analyze the computational complexity for the antenna selection and the generation of joint ZF beam-weight. Finally, we verify the analytic results by computer simulation.
