Power Distribution Algorithm for Multi-User Downlink of JT System

摘要：

For the downlink of MIMO TDD/CDMA mobile radio systems Joint Transmission(JT) which has low receiver complexity is recently proposed. First investigations concerned linear transmitter algorithms and nonlinear transmitter algorithms based on the principle of THP. The nonlinear transmitter algorithms studied by M. Meurer have preferable energy efficient but restricted by coding complexity. In this paper we present a power distribution algorithm in multi-user downlink of linear JT in MIMO system (JT MIMO). First, a model of JT MIMO downlink and interference is introduced, then, we present a joint power distribution algorithm for JT MIMO downlink. By distributing the transmission power of users rationally, under achieving the SINR, minimizes the total transmitted power.
