摘要
将应用于平坦衰落相关信道下的网格退化(LR,latticereduction)算法推广到频率选择性衰落信道中。给出了在频率选择性衰落的相关信道中,采用网格退化算法辅助检测前后最小均方误差(MMSE)检测器的性能比较。实验表明:在具有频率选择性衰落的相关信道中,采用网格退化辅助检测算法能显著地提高系统的检测性能。
Lattice reduction(LR) techniques, which have already are popularized in the MMSE receiver for frequency selective channels. order may result in different system performance. The simulation is between MMSE detector and lattice reduction aided MMSE detector is been used in flat fading coherent channel, It can be found that the different detection presented, in which the system performance evaluated.
