Abstract
In this paper, we investigate the optimal transmit antenna location for distributed antenna systems (DAS) with selection transmission in the downlink. Considering the effects of path loss, shadow fading, rayleigh fading and white Gaussian noise, we first derive the approximate cell averaged outage probability at high signal-to-noise ratio (SNR). Then, we obtain the transmit antenna location by minimizing the approximate cell averaged outage probability. Simulation results validate the analytical results and show that DAS with optimized antenna locations offers smaller outage probability over the traditional co-located antenna system (CAS).
