Multiuser Network Codes based on symmetric matrices

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 codes are a high diversity and ease of scalability to larger network designs. Finite fields has a unique feature of constraining the signal energy and its performance does not deteriorate much when transmitted through fading channels. Results are compared with theoretical evaluations.
