Since the evaluation of multiple-input multiple-output (MIMO) antennas requires full information of its complex radiation patterns as well as propagation channels, its design procedures and analyses are cumbersome and complicated in general. In this letter, the accuracy of a closed-form capacity formula for mean MIMO channel capacity is investigated, where the -parameter of the antenna is needed...
The development of a pixilated semiconductor detector such as CdTe or CdZnTe, which is available for x-ray imaging, has been pursued by many researchers. In the case of x-ray imaging, the photon flux is very high, and thus conventional CT systems adopt energy integration detectors. On the other hand, the reduction of patient dose becomes one of the major issues in state-of-art CT systems. Thus, detectors...
The regression based channel capacity (REC) has been proposed for a simple and efficient evaluation of compact MIMO antennas. By entering the mean effective gains (MEG), correlation of MIMO array elements, and incident wave SNR to the developed regression formula, one can readily estimate the 2 × 2 MIMO channel capacity without a large amount of computer and human resources. The validity of the REC...
A simple and efficient method of the evaluation of MIMO channel capacity has been proposed. First, the channel capacity of a half wavelength dipole array antenna was calculated using a Monte Carlo method by changing incident wave SNR, power difference between two elements, and correlation coefficient. Using the calculated results, a polynomial function of estimating the channel capacity was given...
Digital broadcasting terrestrial services have been spread all over the word, including Europe, North and South America. In Japan, Terrestrial Integrated Services Digital Broadcasting (ISDB-T) system has been adopted. ISDB-T system has a unique feature in that it offers not only high definition television (HDTV) services for fixed reception, commonly referred to as ‘Full segmentation’, but also mobile...
