碩士 === 國立交通大學 === 電信工程系 === 91 === In this thesis, the measurement and characterization of indoor WLAN spatio-temporal radio channel and the influence of the capacity of indoor MIMO channel are presented. The indoor WLAN spatio-temporal radio channel and the indoor MIMO channel are measured by RUSK channel sounder at 2.44GHz and a vector network analyzer at 5.3GHz, respectively. For spatio-temporal radio channel, probability density function of Time-of-Arrival (TOA) and Angle-of-Arrival (AOA) and TOA-AOA joint probability density function are analyzed. The pdf of TOA is exponential decay and the pdf of AOA is uniform distribution in NLOS scenario, but is clusters distribution from indoor to outdoor. For indoor MIMO channel, the capacity in LOS scenario would smaller than in NLOS scenario. Local scatters around the Tx will decrease the capacity. The Tx-Rx distance and corridor environment has little influence to the channel capacity in short distance.
