This paper compares the performance of a relay assisted network to the performance given by a classical macrocell network without the presence of relay node schemes. The capacity enhancement provided by a relaying system as a function of the relay antenna height and the propagation environment surrounding the relay nodes is analyzed and discussed in details. The analysis in this work is based on the theoretical Shannon capacity where both measured/experimental path loss and calibrated path loss ...

this paper describes a wideband radio channel sounder. Such a device is able to measure the complex time-variant impulse response of the propagation channel. The impulse response is obtained by inversion of an optimal multi-sine sequence with flat spectrum and low crest factor. In standard configuration, this device is able to measure the propagation channel impulse response with a maximum bandwidth of 800 MHz in the DC-30 GHz frequency range fulfilling 5G requirements especially for millimeter ...

This paper analyzes the frequency dependency of the radio propagation channel's root mean square (rms) delay spread (DS), based on the multi-frequency measurement campaigns in the mmMAGIC project. The campaigns cover indoor, outdoor, and outdoor-to-indoor (O2I) scenarios and a wide frequency range from 2 to 86 GHz. Several requirements have been identified that define the parameters which need to be aligned in order to make a reasonable comparison among the different channel sounders employed fo...

Millimeter-Wave (mmW) communication systems, capable of achieving high data rates thanks to the large bandwidth available in this frequency range, are a promising 5G technology. Studies in this paper investigate the radio propagation channel at 3, 17 and 60 GHz in an Outdoor environment. Measurements were conducted using a wideband channel sounder to derive channel delay spread (DS). Results do not indicate a clear trend on the behavior of the DS with regards to the frequency. This disagrees in ...

Millimeter-Wave (mmW) communication systems, capable of achieving high data rates thanks to the large bandwidth available in this frequency range, are a promising 5G technology. Studies in this paper investigate the radio propagation channel at 3, 10, 17 and 60 GHz in an Outdoor-to-Indoor (O2I) scenario. Measurements were conducted using a wideband channel sounder to derive channel parameters such as building penetration losses and channel delay spread values. It was observed that signal attenua...

A summary of channel sounding campaigns in the European Horizon 2020 mmMAGIC project is presented in this paper. A comprehensive database of radio channel responses covering radio frequencies up to 100 GHz and various use cases has been established, complementing the on-going fifth-generation channel model development.

Relaying technique is a key technical enhancement in 3GPP LTE-Advanced proposed for the improvement of system performances such as spectral efficiency and throughput. In order to evaluate system performance, propagation path loss models for the links between the Base Station-Relay Station (BS- RS), the Base Station-Mobile Station (BS-MS) and the Relay Station-Mobile Station (RS-MS) must be investigated. This paper compares the Path Loss (PL) models for the RS-MS link to measurement data. The ana...
