Millimeter Wave (mmW) communication has received more and more attention since it can use the massive available bandwidths to improve the rate of wireless networks. In this paper, we will analyze and optimize the performance of mmW communication system with directional cell discovery based on beam scanning. We first model the mmW communication system with beam scanning and then analyze the effect of the number of the scanning beams and the beam gains on its performance. Since changing the number of scanning beams, K, can not only adjust the beam gains but also control the cell searching delay equivalently, K can be optimized to maximum the system capacity and reduce pilot signal overhead. The simulation and analysis results show that there exists an optimal K which not only makes the system capacity maximum but also trade off the cell searching delay and the beam gain.
