Application of second-order statistics of variable fading channels (average level crossing rate and average fade duration) for estimation of time behavior of MIMO-system characteristics is investigated. Mathematical expressions of these statistical parameters for MIMO-system are derived. Verification of the results is conducted using numerical modeling.
Time varying nature of uplink/downlink channels in wireless communications, calls for prior knowledge about the channel parameters in the receiver side. This accounts for different techniques of estimating the parameters of the so called channel between the transmitter and the receiver. In this paper beside using a channel model for a typical multi-input multi-output (MIMO) wireless communication...
In this paper, a novel approach using frame-based iterative channel fading parameters estimation technique from the received data sequence exploiting orthogonal property of the space-time block (STB) code is proposed. For practical implementation of STB code, the receiver requires to estimate these parameters. Regarding this type of estimation, the inherent orthogonal nature of STB code can be exploited...
