In order to evaluate the relay performance for IMT-Advanced systems, the propagation characteristics of relay channels are necessary, especially in urban environments. We conducted wideband relay channel measurements at 2.35GHz in urban environments of China by employing a real-time channel sounder. Three types of links, i.e. base station to mobile station(More)
To enhance the activity of chemi-deposited palladium/nickel foam (Pd/Ni) electrodes used for an electrochemical dechlorination process, silver or copper was deposited electrochemically onto the nickel foam substrate (to give Ag/Ni or Cu/Ni) before the chemical deposition of palladium. The physicochemical properties of the resulting materials (Pd/Ni,(More)
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(More)
The combination of multiple-input multiple-output (MIMO) and relay technology promises to increase coverage and system capacity, while the actual performance of MIMO relay system highly depends on the practical channel conditions. Based on the propagation measurement data in urban environment, we deal with the capacity evaluation for a two-hop(More)
