摘要:
研究了MIMO OFDM系统中LS、LMMSE准则下的导频辅助的信道估计技术.提出了一种基于最优导频设计并结合SVD分解的改进的LMMSE频域算法.仿真结果表明,采用最优导频设计的简化算法在收敛速度、抗噪声性能和降低算法复杂度方面有很大提高.
Abstract:
A channel estimation technology based on pilot assistance under the LS, LMMSE criteria in MIMO OFDM systems was investigated. An improved LMMSE frequency domain algorithm combining optimal pilot design and singular value decomposition (SVD) was proposed. The simulation results showed that the simplified algorithm by using optimal pilot design has greatly improved the performances in convergence rate, anti noise performance and reduced the complexity of algorithm.
