| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Multiple-input multiple-output (MIMO) spatial multiplexing provides very high spectrum efficiency. However, in conventional cellular network (CN), in which antennas are centralized at the center of the wireless cell, the transmission rate of a user close to the cell edge significantly degrades because the received signal-to-noise power ratio (SNR) or signal-to-interference plus noise power ratio (SINR) degrades. Distributed antenna network (DAN), in which many antennas are spatially distributed over the cell, can solve this problem. In DAN, since some antennas can always be visible from an MT with a high probability, the received signal power improves over the entire cell. In our previous works, we showed the channel capacity distribution of MIMO spatial multiplexing in DAN. In this paper, we study the spatial distribution of the throughput of single-carrier (SC) MIMO packet transmission using hybrid automatic repeat request (HARQ) and a near maximum likelihood signal detection in DAN. First, we evaluate, by computer simulation, the spatial distribution of the uplink throughput achievable by DAN and CN in a single-cell environment and show that DAN can significantly reduce the required transmit power compared to CN and it can achieve high throughput over the entire cell. In a multi-cell environment, we discuss the impact of the frequency reuse factor on the uplink throughput of DAN and CN and show that DAN can reduce the frequency reuse factor and achieves higher throughput normalized by the frequency reuse factor compared to CN. | |
