In distributed radio mobile communications system, Remote Antenna Unit (RAU) selection scheme will influence the system performance. In this paper, a selection model is presented for RAU selection in distributed radio system based on soft handoff theories. The selection strategy is based on received signal strength (RSS) measurements and described as a multiple state Markov chain. The RSS threshold is determined by velocity of MS. Performance analysis results show that numeric data achieved from the model are in good agreement with simulation results, which verifies the validity of the model.
