Abstract

Blind equalization and decoding of unitary space-time modulations are considered. A blind adaptive equalization method was put forward for the codes proposed by Hochwald et al. (Sept. 2000). The stationary points of the said method are investigated. A modified version of the algorithm is provided to avoid undesired convergence. A generalized likelihood ratio test decoder is presented for the equalizer outputs. Semi-analytic methods are developed to investigate pairwise error probability with large number of receive antenna assumptions.
