Closed-Form Blind MIMO Channel Estimation for Orthogonal Space-Time Block Codes

Shahbazpanahi, Shahram; Gershman, Alex B; Manton, Jonathan


In this paper, a new computationally simple approach to blind decoding of orthogonal space-time block codes (OSTBCs) is proposed. Using specific properties of OSTBCs, the authors' approach estimates the channel matrix in a closed form and in a fully blind fashion. This channel estimate is then used in the maximum-likelihood (ML) receiver to decode the information symbols. The proposed estimation technique provides consistent channel estimates, and, as a result, the performance of the authors'...[Show more]
