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 Tomlison-Harashima Precoding(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.
