In this paper, the bipartite consensus problems are investigated for multi-agent systems with double-integrator dynamics and antagonistic interactions. We consider bipartite consensus under the given protocol, which means that the absolute value of the position is the same when all the velocities of agents are 0, but the sign may be opposite. When there are no delays, the necessary and sufficient...
Three-dimensional multiple-input multiple-output (3D MIMO) is one of the most promising techniques for the fifth-generation (5G) mobile communication systems. In order to catch the the propagation characteristics of the 3D channel, extensive measurements have been carried out. Although outdoor to indoor (O2I) scenarios is one of the main propagation of 3D MIMO channel, it remains too much work to...
This paper shows the variation of clusters with the increasing number of antennas. The data was collected from the massive MIMO mobile measurement at 3.5 GHz, in line of sight (LoS) and non line of sight (NLoS) conditions, respectively. And the virtual measurement method is used to form the 64-element, 128-element and 256-element virtual antenna array from the 32-element antenna array. After estimating...
To meet the rapid increasing demand of the high data rate communication, millimeter wave communication system has attracted considerable attention. In this paper, a millimeter wave wideband channel measurement with mobility in urban micro-cell mobile communication scenario at 28 GHz is presented for the purpose of capturing the channel characteristics. Based on the measured data, we analyze the path...
In this paper, we investigate the statistical characteristics of the three dimensional (3D) multiple- input multiple-output (MIMO) channels and their dependency on the dynamic range in channel impulse responses (CIRs). Our study is based on empirical results obtained from the 3D MIMO channel measurement campaigns at 6 GHz in a typical urban macrocell outdoor-to-indoor scenario. The space-alternating...
In this paper, the channel propagation measurements have been performed in indoor scenario at 3.5, 6, 14, 23, 26 and 28 GHz. The measured cases include line-of- sight (LOS) and non-line-of-sight (NLOS) propagation. Statistical results and comparative analysis are presented in this paper, including path loss (PL) and root mean square (RMS) delay spread (DS). Both floating-intercept (FI) path loss model...
The millimeter-wave band will be one of the most key components in the next generation wireless communication system. In this paper, a radio channel measurement was conducted in an indoor office environment at 28 GHz with 500 MHz bandwidth. The channel sounder with the clock synchronization was used to measure in both line-of-sight (LoS) and none- line-of-sight (NLoS) scenarios. The channel impulse...
In this paper, the mobile channel propagation measurements at 3.5 GHz and 6 GHz have been performed in urban micro-cell scenario in the city of China. The measured cases include line-of-sight (LOS) and non- line-of-sight (NLOS) propagation. Statistical results and comparative analysis are presented in this paper, including power delay profiles (PDPs), path loss (PL), coverage, and root mean square...
In this paper, we present the small scale characteristics of indoor office scenario based on the channel measurement at 14 GHz with 250 MHz bandwidth. The measurements were operated at more than 100 receiver locations including LOS and NLOS cases over distances up to 55 meters by utilizing a sliding correlator sounder with 125 mega-chip per second (Mcps). Besides, highly directional horn antennas...
