DasGupta, Jishu and Ziri-Castro, Karla and Suzuki, Hajime (2007) Capacity analysis of MIMO-OFDM broadband channels in populated indoor environments. In: 7th International Symposium on Communications and Information Technologies (ISCIT 2007:) , 16-19 Oct 2007, Sydney, Australia.
This paper presents the results of dynamic channel capacity measurements for a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system in two populated indoor environments with and without line-of-sight (LoS). The experiment used 4 sending and 4 receiving antennas and 114 sub-carriers at 5 GHz as per draft IEEE 802.11n. MIMO-OFDM channel capacity is analysed both with fixed receiver signal-to-noise ratio (SNR) and fixed transmitter (Tx) power criteria. It is found that fixed SNR capacity increased while fixed Tx power capacity decreased in both environments by the presence of pedestrian. It is also revealed that the spread of the capacity cumulative distribution function (CDF) increased due to the pedestrians in both environments with both criteria.
