In this study, novel designs of embedded space–time multiplexing codes are presented. The space–time codes are constructed initially based on the decomposition of normal matrices that produce diagonal structures. The eigenvalue decomposition of circulant matrices, a type of normal matrices, can generate these codes. A key constraint in the design is that(More)
In this paper, we propose a Multi-user (Mu)-Multidimensional system in a wireless communication scenario. This design uses precoding and reordering of data in multiple dimensions. Hence it produces an embedded diversity due to the linear combination of all input elements. However, because of this precoding, there is a constellation expansion that needs to(More)
Cooperative communications is a candidate technology for future network designs. In this paper, a design of distributed network coding is introduced. The proposed design are based on algebraic constructions in Finite Field using symmetric Matrices. These set of codes are an alternative to Generalized Dynamic Network Codes (GDNC). A rich feature of these(More)
