description In this paper a spatially and temporally clustered channel model is proposed to be applicable to Wireless Local Area Network (WLAN) MIMO systems based on circular antenna arrays (UCA). Properties of multipath taps along with angular and power values of clusters are included in this model to consider wideband signal with frequency selective fading channels. Link performance of systems that utilize UCA at both link ends, the access point (AP) and mobile associated stations (STAs) are investigated. Standard IEEE802.11 TGn channel scenarios are used to simulate different realistic environments. Characteristics of ergodic channel capacity versus azimuth orientation of UCA arrays are analyzed and compared with that of uniform linear array (ULA). Also, the water filling (WF) power allocation scheme performance is investigated under different conditions. Performance of VBLAST UCA bases receivers in combination with successive interference cancellation are also presented for different TGn channel models by utilizing the proposed channel model.
