In this paper, the results of distributed multipleinput multiple-output antenna system (MIMO DAS) capacity measurements are presented. Until this point, literature about MIMO DAS considers only theoretical channels. The novelty of this paper comes from applying actual measured radio channel to MIMO DAS. In MIMO DAS, the coverage is obtained by using several(More)
Indoor MIMO measurements in a laboratory environment, covering both line-of-sight (LoS) and obstructed lineof-sight (OLoS), are reported. Comparison of data taken at 2.55 and 5.25 GHz reveal subtle differences in temporal and angular characteristics. Multipath appears in clusters, which can be attributed to specific scattering/reflection areas in the(More)
This paper analyzes the asymptotic distribution of the channel eigenvalues and the asymptotic ergodic channel capacity using measured multiple-input multiple-output (MIMO) data. A realistic propagation environment in the presence of spatial fading correlation under an outdoor-indoor scenario at 5.25 GHz, which has important applications for data(More)
In this paper, the performance of a multiple-input multiple-output (MIMO) downlink (DL) with the space-time turbo coded modulated (STTuCM) transmission and with adaptive modulation is studied in the system level. Furthermore, the link-to-system (L2S) level interface will be examined. Research is carried out with a dynamic system level simulator where(More)
Performance evaluation of enhanced link adaptation method for MIMO-OFDM systems with limited feedback using measurement based channels and a stochastic channel model is presented in this paper. In particular, impact of practical channel estimation and feedback errors on link performance is analyzed. An adaptive spatial and modulation scheme selection(More)
