Dependency of MIMO Channel Capacity on Power Azimuth Spectrum for Multi-band Multi-antenna Mounted on Handheld Device
Yoshiki Okano, Keizo Cho (DoCoMo) AP2007-121
Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we investigate the dependency of the MIMO channel capacity on the power azimuth spectrum for the multi-band and multi-antennas mounted on the handheld device considering the multi-channel radiation patterns, which were acquired in the anechoic chamber, and the power azimuth spectrum as a feasibility study on the antennas for mobile terminals toward the application of MIMO transmission techniques into the systems beyond 3G. Evaluation criteria include the effective received power, spatial correlation between antennas, eigenvalue of the correlation matrix for MIMO channel, and MIMO channel capacity. We compare the performance of multi-band and multi-antenna configuration mounted on the actual handheld device with that for the half-wavelength dipole array considering that the antennas must be equipped with the size limitation in the mobile terminal. In addition, we clarify the altered characteristics according to the power azimuth spectrum based on the spatial channel model of the uniform model and cluster model. Also considered are the effect of operating frequency bands, usage situations of the mobile terminal and the signal-to-noise-ratio.
