摘要: Coordinated Multi-Point (CoMP) transmission or reception is an efficient way to reduce inter-cell interference, improve the spectrum efficiency and coverage in LTE-Advanced systems. Compared with other CoMP technologies, Joint Transmission (JT), which carries out precoding based on channel information, can achieve better system performance gain. In this paper, a scheme termed projection-based power allocation proposed, combines joint space domain frequency domain. The simulation results for TD-LTE-Advanced systems show that outperforms traditional equal without projection bit error rate (BER) subject constraints total obviously.
