Abstract The energy efficiency of coordinated transmissions in multi-cell distributed antenna systems (DAS) was analyzed with a focus on the antenna element correlation within each distributed antenna cluster to maximize the system energy efficiency through inter-cell coordinated optimization of the input covariance matrices. The system uses only the slowly varying channel statistics including the large-scale channel state information at the transmitter and the transmit antenna element correlation characteristics. The optimization problem is non-convex and, therefore, is hard to solve. The method of successive Taylor expansions was used to recast the problem into a succession of quasi-convex fractional optimization sub-problems, which were then further converted to tractable equivalent convex forms via the fractional programming approach. An iterative scheme was then used to address the original optimization problem. Simulations show that this scheme provides improved system energy efficiencies compared to existing schemes.
