Abstract

This paper presents a multiple-input multiple-output (MIMO) relay channel model based on the International Telecommunication Union (ITU) generic channel model for the test evaluation of radio interface technologies (RITs). Each link is modeled by the conventional point-to-point channel model with specific parameter set. A MIMO relay measurement in a typical urban micro-cell environment at 2.35GHz with bandwidth up to 50MHz was performed, and the collected data are compared with the derived model. Capacity values in amplify-and-forward (AF) and decode-and-forward (DF) relay modes are selected to be the comparing metrics. Furthermore, another relay channel model with channel characteristics following Rayleigh or Rice distribution is provided as a baseline for comparison. It turns out that the proposed ITU generic channel model shows good comparison to the measurement data in this specific environment, for the capacity of modeled channel is quite similar to that of the measurement channel in both AF and DF modes.
