Das Gupta, Jishu and Ziri-Castro, Karla and Suzuki, Hajime (2007) Dynamic range analysis on MIMO-OFDM broadband channels in a populated time-varying indoor environment. In: ATNAC 2007: Next Generation Networks: Enabling Closer International Cooperation, 2-5 Dec 2007, Christchurch, New Zealand.
We investigate the variations on channel capacity for a multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system due to the presence of pedestrians. Capacity dynamic range is measured for 2x2, 3x3, and 4x4 antenna configurations in line-of-sight (LoS) and non-LoS (NLoS) environments using fixed signal-to-noise ratio (SNR) and fixed transmitted (Tx) power. It was found that the fixed SNR capacity increased while fixed Tx power capacity decreased in both environments in the presence of pedestrians. The results show larger dynamic range values for LoS over NLoS and similar dynamic range values for different antenna configurations.
