Simultaneous Wireless Information and Power Transfer (SWIPT) systems enable mobile phones to live much longer in the network. In this paper, we formulate an optimization problem to best design a multi-user multi-antenna Broad-Cast (BC) system by simultaneously maximizing the sum of harvested energy and minimizing the sum Mean Square Error (MSE) for symbol detection at each receiver. This design problem is then recast as a multi-objective problem with the Difference of Convex (DC) bilinear structure. The final design problem is solved using the Alternating Convex Search (ACS) method and the Penalty Convex-Concave Program (PCCP) procedure. Simulation results are extensively undergone to assess the performance of the proposed algorithms.
