摘要：Linear transceiver designs are investigated for distributed two-way relaying networks,which aim at minimising the WeightedMean Square Error(WMSE) of data *** forwarding matrices at relays andequalization matrices at destinations are jointly *** overcome the challenginglimitations introduced by individual powerconstraints,a Semi-Definite Relaxation(SDR)called element-wise relaxation is proposed,which can transform the original optimizationproblem into a standard convex *** this research,two-way relaying isunderstood from a pure signal processing perspective which can potentially simplify thetheoretical ***,simulation resultsare used for assessing the performance advantage of the proposed algorithm.
