Abstract— In this paper, collocated and distributed spacetime block codes (DSTBCs) which admit multi-group maximum likelihood (ML) decoding are studied. First the collocated case...

: Cyclic Delay Diversity (CDD) was introduced in 2001 to obtain spatial diversity in an Orthogonal Division Multiplexing (OFDM) based transmission system. In contrast to Space-Time...
