Abstract

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.

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.
