摘要：

In　this　paper,　a　novel　WLAN　system,　Cognitive　WLAN　over　Fiber　(CWLANoF),　is　introduced　in　the　first　place.　Moreover,　when　CWLANoF　has　more　channels　than　STAs,　a　new　channel　allocation　scheme　is　proposed　using　the　Hungarian　algorithm,　which　is　demonstrated　to　be　the　optimal　one.　Furthermore,　when　CWLANoF　has　fewer　channels　than　STAs,　it　is　possible　for　more　than　one　STA　to　share　the　same　channel　simultaneously　based　on　the　new　features　of　CWLANoF.　And　the　power　control　scheme　is　proposed　for　this　kind　of　sharing,　considering　efficiency　and　fairness.　Finally,　extensive　simulation　results　illustrate　the　significant　performance　improvement　of　the　proposed　channel　allocation　scheme　and　power　control　scheme.
