Abstract
Based on maximum desired signal criterion, a novel single selection transmission scheme (SSTS) is proposed. In this case, the bit error rate (BER) of downlink distributed antenna systems in multicell environment is investigated. In particular, non-central limit theorem is adopted for SSTS to embody the effect of short-term fading on interference, where the variance of interference plus noise is considered as random variable with changeable variance influenced by the short-term fading. It is assumed that the channels suffer from independent identical Rayleigh fading together with propagation pathloss, and the closed-form expression of BER is derived. Extensive simulations are carried out to validate the theoretical derivation.
