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...
Geometry-based stochastic model (GBSM) of multiple input multiple output (MIMO) channel describes the channel impulse response (CIR) in the sense of rays and clusters, which obey the empirical distributions. Thus, the correlation between MIMO sub-channels is not explicitly defined, which makes it difficult for GBSM to predict channel capacity accurately. Facing the increased antenna number of massive...
Three dimensional (3D) Multiple Input and Multiple Output (MIMO) is one of the most promising techniques for the 5th Generation (5G) mobile communication systems. Thus there is an urgent need for one reliable 3D MIMO channel model to research and evaluate 3D MIMO techniques. In this paper, we focus on the statistic characteristics of elevation angle in urban microcell (UMi) and propose a novel elevation...
Based on the channel measurement in a typical indoor environment, wideband multi-input multi-output (MIMO) channel capacity analysis result is reported in this paper. A series of non line-of-sight (NLOS) and LOS measurement positions are planned for capacity comparison in different propagation conditions. For fixed received signal-to-noise ratio (SNR), slight average capacity loss in LOS cases is...
For real time service, not only the data rate, but also the packet delay should be guaranteed. In this paper, by exploiting the queue status information and channel status information, a novel framework of joint spatial-frequency scheduling for real time service in MIMO-OFDMA system is proposed, and some joint spatial-frequency scheduling algorithm is proposed based on modified largest weighted delay...
