Distributed antenna systems (DAS) have been paid much attention for low outage probability in future wireless communications, since it can reduce the radio transmission distance between the transmitter and the receiver. In this study, the authors present a study on DAS for two different transmission strategies: blanket transmission scheme and single selection transmission scheme (SSTS). The outage probabilities of the two schemes are re‐analysed over Rayleigh fading adopted non‐central limit theorem (NCLT) and compared with central limit theorem (CLT) method. Moreover, the authors derive analytical expressions of the outage probability for both no shadowing and shadowing scenarios, respectively. Then, an energy efficient power allocation strategy is proposed. Finally, extensive simulation results validate the theoretical analysis and demonstrate the proposed NCLT method can describe the system performances more accurately.
