The practicality of interference alignment with measured IEEE 802.11ac wireless channels

Interference is known to cause the performance degradation of the wireless network. To solve the interference problem, cooperative transmission scheme such as interference alignment (IA) is required. Channel state information (CSI) among IA participation nodes should be essentially obtained to implement IA. By implementing the IA prototype with obtaining the real environment CSI, we can check the performance of our developed IA algorithms and compare the IA and non-IA case.
