Abstract
Channel estimation in the (2 × 1) Alamouti space-time block coded systems can be performed blindly from the eigendecomposition (or diagonalization) of matrices composed of the receive antenna output 4th-order cumulants. In order to estimate the channel, we will propose to choose the cumulant matrix with maximum eigenvalue spread of cumulant-matrix. This matrix is determined in closed form. Simulation results show that the novel blind channel identification technique presents a satisfactory performance and low complexity. © Springer-Verlag Berlin Heidelberg 2009.
