Recently, the multi-hop cellular networks have been widely studied in order to enhance the cell performances such as the cell
capacity. While most of these works merely use the multi-hop methods instead of direct transmission without considering the
co-channel inter-cell interference, signal transmission mode and the effects of the number of antennas. With the consideration
of above important elements, this paper proposed an improved cellular system with multi-relay amplifies-and-forward (AF) cooperative
transmission scheme and the corresponding capacity expression is derived under the corresponding environment. By using the
potential space diversity and selecting relays based on maximizing the capacity, the cellular system capacity can be improved
effectively. The simulation results show that with the assistance of optimal selected relays, the improved cooperative cellular
system capacity with multi-relay AF transmission scheme performs better than single-hop cellular system. 相似文献
