[C19] W. J. Park and H. J. Yang, “System-level performance evaluation of multi cell two-way relay networks with fractional frequency reuse,” in Proc. International Conference on ICT Convergence (ICTC), Busan, Korea, Oct. 2014, pp. 936-940. Abstract Two-way relaying has been known to double the spectral efficiency of the one-way relaying scheme in a single cell system. In this paper, we observe… Continue reading
