Abstract

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.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
