Abstract：Outage probability is an important parameter in wireless communication systems. This paper studies the system outage probability in the Distributed Antenna Systems (DAS). Firstly, this paper establishes a composite channel model which takes into account three factors such as path loss, lognormal shadowing and Rayleigh fading. Based on the established channel model, the Signal-to-Noise Ratio (SNR) of Mobile Station (MS) over a given position is derived. Then, an uplink transmission expression of the outage probability for the MS over a given position is derived by employing the selective combining. Further, considering the distribution of MSs in the cell, a closed-form expression of the system outage probability is obtained. Numerical results show that the closed-form expression of the system uplink outage probability can match with the simulation results very well.
