| Abstract(in English) | High density deployment of WLAN (Wireless LAN) is resulting in throughput degradation caused by co-channel interference among APs (Access Points) and STAs (Stations) in urban areas. In order to solve this problem, it is proposed to use adaptive directional antenna at AP to improve throughput performance when omnidirectional antenna is used at STAs. If AP knows channel state information between AP and STA, AP can control each subcarrier phase to enable coherent combining reception of each subcarrier at STA thus received SINR at STA is expected to be improved. This report evaluates SINR and transmission rate improvement of the downlink from AP to STA in indoor WLAN using a ray-tracing method, assuming that two APs using the same channel frequency are closely located. |
