“…The path-loss prediction model in this paper only assumes uniform angular distribution and that the line-of-sight (LOS) part exists which is followed by diffuse components. These assumptions were also verified by the numerical models proposed in [12]- [14].…”

Abstract-A simple approach of path-loss and root mean square delay spread prediction for indoor propagation environment is developed based on the room electromagnetics theory. The indoor room environment is interpreted as a lossy cavity, which is characterized by the diffuse scattering components caused by the walls and surrounding obstacles, and a possible line-of-sight component. Simplicity, speed of the algorithm and good accuracy are among the advantages of this approach. To apply the method, it only requires the knowledge of the dimensions of the room and the reverberation time, which can be easily obtained from one measurement of the powerdelay-profile in the investigated environment. For experimental validation, path-loss measurements at two different transmission frequencies, and wideband measurements from 0.8 to 2.7 GHz were conducted in two rooms of an industrial environment. The theoretical results from the path-loss and root mean square delay spread prediction algorithm show good match with the measurement results.

“…By interpreting the indoor room as a lossy cavity, the room electromagnetics based prediction method assumes uniform angular distribution and that the line-of-sight (LOS) component exists with the followed diffuse components. These assumptions were extensively verified by various field measurements [1], [13] as well as the numerical model [16]- [18]. This paper demonstrates the use of only one wideband measurement for the extraction of reverberation time in addition to some knowledge on the propagation environment to provide accurate predictions of various channel characteristics parameters, which is the main contribution of the paper.…”

The successful design of communication systems generally requires knowledge of various channel characteristic parameters. This paper utilizes the reverberation time extracted from single-snapshot wideband measurement to estimate different indoor propagation parameters based on the room electromagnetics theory. The indoor room environment is conceived as a lossy cavity that is characterized by the diffuse scattering components resulting from the surrounding walls and objects and possibly a line-of-sight (LoS) component. The main advantages of the room electromagnetics based approach are simplicity and good accuracy. The approach needs only one wideband measurement in order to extract the reverberation time in addition to some dimensional information on the investigated room to predict various important channel parameter of great importance. The measurements show good agreement with the theoretical predicted results.

“…Identical dual-polarised patch antennas are used for Tx and Rx. These antennas operate at 1.35 GHz with 80 MHz bandwidth, 80°b eam width at −3 dB (in azimuth and elevation), 7 dBi gain and typical nominal voltage-standing wave ratio ≤ 2 in the band of interest [45]. The measured XPD of the antennas in an anechoic chamber is 15 dB.…”

The polarimetric massive MIMO radio channel of an indoor Line-Of-Sight (LOS) scenario is investigated at 1.35 GHz using a real-time radio channel sounder. The 8 × 12 massive MIMO transmitter is constructed using a hybrid architecture including a vertical uniform linear array (V-ULA) translated at different horizontal positions forming a virtual, yet realistic, uniform rectangular array. The performance of the system is evaluated with 6 users distributed in the room for different polarization schemes and receiver orientations using propagation channel-based metrics (such as receiver spatial correlation, Rician factor, etc.) and systemoriented metrics such as sum-rate capacity and signal to interference and noise ratio. The results show a clear dependence of the performance to the polarization schemes and receiver orientation. Furthermore, it is concluded that the additional degree of freedom brought by the polarization diversity can contribute to improve spectral efficiency, paving the way for further capacity enhancements in massive MIMO systems.
