Abstract :
Decision directed channel estimation is investigated in this paper. For systems with multiple transmit antennas, high computation complexity of the inversion of a data-dependent matrix hinders the application of optimal channel estimation. An iterative method is introduced to avoid the matrix inversion. Performance of the proposed method is demonstrated by simulation results.
