Research on Communication Transmission based on Differential Protection Service of Distribution Network

In this article, a short packet communication means based on differential protection is studied. A j oint optimization framework is proposed to maximize the summation rate. Since the question is non-convex, an alternate majorization algorithm is proposed to deal with the question. Firstly, the optimization problem is decoupled into two subproblems, the precoding vector is optimized by continuous convex approximation, and the error probability optimization subproblem is solved by Lagrange duality. Through simulation results, we verify that with the successive convex approximation, we can realize a bigger realizable rate than the ZF and MRT methods, which shows our research has important potential in the transmission of differential protection.
