N2 - Considering the fairness between the users in physical-layer multigroup multicasting, the Max-Min Fairness (MMF) precoding problem is investigated under the per-antenna power constraints. A suboptimal precoding algorithm is proposed by decoupling the problem into a precoding direction vector design problem and a power allocation problem. Particularly, the SLNR (Signal to Leakage plus Noise Ratio) metric is considered in the precoding direction vector design to properly mitigate the inter-group interference. Moreover, aiming at the MMF criterion, the power allocation procedure can guarantee fairness between users. The simulation results show that the proposed algorithm has less complexity than the primary MMF algorithm at the cost of some performance loss, while has better performance than a low complex algorithm, and consequently provides a solution for the tradeoff between complexity and performance.
