Abstract :
By deriving the upper capacity bound of the polarized distributed MIMO system on Rician channel, the suboptimal power allocation scheme is presented by applying Lagrangian optimization. The suboptimal power allocation is based on the path loss fading information, and it needs less feedback information than other power allocation schemes which are based on channel mean or covariance matrix. The suboptimal power allocation scheme is applicable for arbitrary antenna number at both the transmitter and receiver sides. The proposed power allocation solution has a closed-form expression and has a water-filling interpretation. Simulation results reveal the proposed power allocation scheme performs almost the same as the optimal solution with little difference.
