In this paper,we investigate the energy efficiency and power allocation problem for distributed multiple-input multiple-output(MIMO)system with beamforming.Given the maximum transmit power limit per distributed antenna(DA)port,a constrained optimization problem is constructed to maximize the energy efficiency(EE).Because of the non-convex nature of the problem,we transform the constrained optimization problem with high complexity into a standard convex optimization problem through the fractional programming theory.
