| 摘 要： | 在LTE-Advanced（LTE-A）系统中,针对目前多用户协作多点传输中常用的预编码算法不能在消除用户间的干扰和自身天线之间干扰的同时考虑系统噪声影响这一现象,提出两种优化的算法：一种是将BD算法与MMSE算法结合;另一种是在SLNR算法的基础上再次利用ZF算法.这两种优化算法都是在消除所有干扰的基础上同时考虑噪声影响的一种方案,仿真结果表明,这两种优化算法可以有效的降低系统误码率,提供了系统性能.

| Abstract: | In the LTE - A system, the common precoding algorit）nn can not eliminate the interfer- ence between the inter user interference and its antenna while considering the influence of the system noise , I put forward two kinds of optimization algorithms： one is the BD algorithm combined with the MMSE algorithm; the second is the use of ZF algorithm based on SLNR algorithm. These two kinds of optimization algorithms is a kind of scheme considering the noise influence in the foundation to eliminate all interference, simulation results show that, these two algorithms can effectively reduce the bit error rate of the system, provides the system performance. |
