为了提高LTE-Adwanced系统边缘用户的吞吐量和性能，本文在协作多点传输的基础上提出了两种联合处理的算法，这两种算法分别采用全局预编码和间接预编码的方式，把来自不同小区的干扰信号联合处理使其成为有用信号，仿真结果表明两种算法都能很好的提高边缘用户的性能。

In orderto improve throughput and system performance at the cell edge user of the LTE-A systerms ,two joint precoding algorithms was proposed for coordinated multi-point(CoMP)transmission systems based on the existing methods,the first algorithm was used to global precoding,and the second algorithm was used to Indirect precoding,this joint processing make interference signals in different cells to become useful signal,simulation results has shown that the two algorithms can be very good to improve the performance of the cell edge user.
