- W2569806291 abstract "Recently, the high speed data transmission is requested by the appearance of various applications in the upcoming cellular phone service. The mobile communication system is developing beyond 3G which is the broadband and high speed in the high dimension, then the MIMO system is expected for efficient improvement use of the frequency. In this paper, we investigate four antennas combined through analog phase shifters provided by two output ports to the receiver to obtain large capacity by setting various phase differences. As the method to select the optimum phase difference, we select the phase condition at the RSSI level [1]. As another approach, this paper propose that the optimum phase difference is decided by the correlation coefficient derived by the complex radiation pattern to obtain channel capacity higher than that of the RSSI level. We also confirm the validity of the correlation coefficient method by considering the presence of a simple shape of the human head model." @default.
