Correlation analysis of MIMO channel measurement parameters under 781MHz environment

In the next generation of mobile communication systems, high data rates and high capacity will be possible if multiple antennas are used at new frequencies. This paper presents the correlations between channel parameter path loss (PL), root mean square delay spread (DS), angular spread (AS), and K-factor established based on channel measurements. The channel measurements were performed in a 781MHz LOS/NLOS environment. To avoid interference from Korean DTV broadcasting, we measured the channel characteristics in urban/rural/suburban areas on Jeju Island using a channel sounder and 4×4 antennas. The correlations between channel parameter show that the wireless channel characteristics can be determined and effective communication system design can be produced for use in similar environments.
