This paper provides concept of data transmission protocol for millimeter wave (mmWave) wireless systems operating in Non-Line-of-Sight environment. This concept is designed to provide an effective and practical functioning of Multiple-Input Multiple-Output (MIMO) transmission mode that exploits combination of Singular Value Decomposition (SVD) of channel matrix and non-adaptive beamforming. The proposed...
In this paper, dynamic system level simulation methodology of mobile WiMAX (IEEE Std 802.16e) is described. The system level simulations scenarios (channel models, pathloss and shadow fading, sectorization, frequency reuse planning, system loading, etc) will be introduced. Evaluated performance of mobile WiMAX system such as signal-to-interference + noise ratio distributions, spectral efficiency and...
In present paper we have investigated a co-channel interference cancellation technique based on the tracking a limited number of strongest interferers only. With the assumption of synchronous base stations operation with overlapping but different training signals (pilots). Kalman filtering may be used for interfering channels estimation and further calculation of interference correlation matrix. This...
