In this paper, the blind and semiblind channel estimation and equalization are investigated for zero-padding single-carrier block transmission (ZP-SCBT) systems using second-order statistics. Unlike the conventional channel estimation techniques, the proposed approach focuses on identifying the inverse of the channel impulse response rather than the channel response itself by skillfully exploiting...
Statistical properties of the channel condition number is important in performance analysis and design of communication systems. In this paper we study the condition number distribution of complex non-central correlated Wishart matrices, relevant for spatially correlated Ricean MIMO channels and detection performance in cognitive radio. We present an approximation framework which is utilized to calculate...
In this paper, we consider a large system analysis of regularized channel inversion (RCI) beamforming for MISO broadcast channels (BC) with transmit-side channel correlation. In the analysis, we assume that both the number of users and transmit antennas grow unbounded with a constant ratio. We also assume that the channel correlation model is separable. Under this channel condition, we are particularly...
This paper derives analytical expressions for the eigenvalues of so-called gamma-Wishart random matrices, which arise in the context of multiple-input multiple-output (MIMO) transmission over land-mobile-satellite (LMS) communication channels. Such matrices are representative of complex noncentral Wishart matrices, but with randomly varying noncentrality parameter following a distribution closely...
