Abstract
This paper considers infrastructure to vehicle communications using Advanced-LTE. The paper compares the downlink throughput performance experienced by mobile users in an urban-macro-cell in cases of 2D and 3D channel models, where the impact of the 3D component on MIMO performance is investigated. Recently there has been strong interest in extending the MIMO processing from the azimuth dimension to include the elevation plane. Therefore, a 3D channel model is required in the evaluation of elevation MIMO performance. Bit level simulation is performed for the downlink physical shared channel (PDSCH) in LTE-A operating at 2.6GHz. Results indicate the accuracy of the 3D channel model and implies correct estimation of the 3D channel. The difference in the small scale parameters for the SISO case and the lower spatial correlation parameters for the MIMO case result in higher predicted capacity for the 3D channel model. The study has been carried out for different mobility speeds, packet sizes and MCSs modes.
