Accuracy analysis of GO/UTD radio-channel modeling in indoor scenarios at 1.8 and 2.5 GHz

Experimental estimation of wide‐band radio channel parameters with the use of a spectrum analyzer and the Hilbert transform

“…This fact confirms that the use of the method based on the Hilbert transform is accurate enough to measure the mean values of these relevant parameters. Furthermore, the measured values in Table 1 are in agreement with those obtained in similar environments, in the same building, obtained by using the HP-Exact method as reported in [4].…”

“…The 50-⍀ characteristic impedance can be obtained, from simulation software Linecalc, by selecting proper values of W C and S C . In [4], the input impedance matching of the CPWG-fed patch antenna is made by adjusting the width of the patch. However, in this article, the width and length of the patch antenna are the resonant edges of the proposed dual-frequency patch antenna.…”

Capacity bounds and estimates for the finite scatterers MIMO wireless channel

“…2, from which the channel matrix was computed using (1), (2), and (18). Hence, capacity was calculated by performing a singular value decomposition on and using (7). A capacity distribution is obtained by repeating this procedure for many randomly chosen instances of scatterer locations and path gains.…”

“…Raleigh and his co-workers [3], [4] have made use of a more complete spatiotemporal version of the model to devise optimum spatiotemporal signalling schemes over a time-dispersive MIMO channel. The spatial,or geometrically-based single-bounce model [5], [6] is in effect a special case and ray-tracing models [7] are also closely related. The concepts behind the model are in fact implicit in the well-known GWSSUS model of the scalar time-dispersive multipath model [8].…”

A sensitivity study of ray-tracing based wireless channel simulators using field measurements

“…For most outdoor scenes the wireless industry relies on empirical models because such models need significantly less input parameters and provide enough detail of the channel for most applications. Most of the reports on validation of ray tracing based channel simulators [1][2][3] have focused on the accuracy of the tools or models under development and not much attention has been paid to sensitivity analysis.…”
