摘要:
为了提高协作通信的增益，通常使用有限反馈技术来有效地传输信道状态信息。从移动台码本中选择码字对信道方向信息( CDI)量化，量化后的信道方向信息对于进行预编码或波束赋形是必要的信息。使用信道矩阵来构建信道方向矢量( CDI)，采用多种码字选择方案对CDI进行量化。联合码字选择方案存在相位模糊，为此提出了一种带有相位模糊反馈的联合码字选择方案。仿真表明，带有相位模糊反馈的联合码字选择能很大改善CoMP系统性能
Abstract:
To improve the promised benefits of CoMP transmission,it is necessary for limited feedback to convey channel state informa-tion. Codewords selected from MSs are used to quantify Channel Direction Information (CDI). It's very important for precoding or beamforming to quantify CDI. Use channel matrix to construct CDI,present several kinds of codeword selection schemes to quantify CDI. There exits to be phase ambiguity in joint codeword selection. Thus propose joint codeword selection scheme with phase ambiguity feed-back. Simulation results are provided that joint codeword selection scheme with phase ambiguity feedback can largely improve perform-ance of CoMP system
