A non-coherent distributed space-time coding scheme for wireless relay networks is presented. The scheme is the counterpart of non-coherent coding based on Grassmann codes, for cooperative wireless networks with relays. Special classes of Grassmann codes obtained from unitary codes, such as Alamouti or Sp(n) codes, are used as non-coherent distributed space-time codes. The scheme is recursively extended to construct non-coherent distributed space-time codes of large lengths.
