As a promising technique, distributed antenna systems has attracted much research attention in the past few years. In this paper, an optimal antenna placement criterion is proposed to maximize the lower bound of the cell average ergodic capacity. In the analysis, per-antenna power constraint (PAPC) is considered and the single transmit selection strategy (where just one distributed antenna is used) is used. The numerical results demonstrate the significant performance gain of the proposed system topology over the random DAS and CAS, which proves the rationality of the proposed criterion.
