摘要 针对频率选择性衰落信道下的分布式空频编码协同通信系统,提出了基于导频辅助的各种频域信道估计算法,包括最小二乘、线性最小均方误差、低阶近似线性最小均方误差算法,并给出了相应的均方误差性能表达式。理论分析和仿真结果表明本文提出的信道估计算法在协同通信系统中具有很高的实用性和精确度。 Several pilot-assisted frequency-domain channel estimation algorithms are proposed for distributed space-frequency coded cooperative communication system over frequency-selective fading channels, including least square （LS）, linear minimum mean square error （LMMSE）, and low-rank LMMSE estimation algorithm （Lr-LMMSE）. The mean square error expressions of the proposed algorithms are also derived. Theoretical analysis and simulation results confirm the high practicality and accuracy of the proposed channel estimation algorithms in the cooperative communication system.
