Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: ,  consider a two-hop one-way relay network for multigroup multicast transmission beten long-distance users, in which the relay is equipped with multiple antennas, while the transmitters and receivers are all with a single antenna. Assuming that the perfect channel state information is available,  study amplify-and-forward (AF) schemes that aim at optimizing the max–min-fair (MMF) rate.  begin by considering the classic beamformed AF (BF-AF) scheme, whose corresponding MMF design problem can be formulated as a rank-constrained fractional semidefinite program (SDP).  show that the gap beten the BF-AF rate and the SDR rate associated with an optimal SDP solution is sensitive to the number of users as ll as the number of por constraints in the relay system. This reveals that the BF-AF scheme may not be ll suited for large-scale systems. , therefore, propose the stochastic beamformed AF (SBF-AF) schemes, which differ from the BF-AF scheme in that time-varying AF ights are used.  prove that the MMF rates of the proposed SBF-AF schemes are at most 0.8317 bits/s/Hz less than the SDR rate, irrespective of the number of users or por constraints. Thus, SBF-AF can outperform BF-AF especially in large-scale systems. Finally,  present numerical results to demonstrate the viability of our proposed schemes.
