Multiple-input multiple-output (MIMO) spatial multiplexing can increase the transmission rate without bandwidth expansion. However, in cellular networks (CNs), the transmission rate of a user close to the cell edge significantly degrades because the received signal-to-interference plus noise power ratio (SINR) degrades due to the presence of strong co-channel interference (CCI) from neighboring cells. Distributed antenna network (DAN), in which many antennas are spatially distributed over the cell, is suitable for MIMO spatial multiplexing because the received SINR improves over the entire cell. In this paper, we discuss the impact of the frequency reuse factor on the downlink channel capacity of DAN-MIMO spatial multiplexing in a multi-cell environment and compare the channel capacity with CN. Assuming the block transmission with cyclic prefix (CP), we derive a channel capacity expression and then, derive the optimal transmit power allocation for DAN-MIMO spatial multiplexing. We evaluate the channel capacity distribution by Monte Carlo numerical computation method to show that DAN can reduce the frequency reuse factor and achieves higher cell channel capacity compared to CN. |
