中文摘要：

最近质点滤波器被提出用作贝尔实验室分层空时（BLAST）结构的硬判决检测方法。给出了BLAST结构的等价白化滤波器输出（WFO）模型和等价动态状态空间模型（DSSM），由DSSM推导出BLAST结构的软判决质点滤波器检测方法一随机M算法，最后将该方法应用于Turbo—MIMO系统并给出仿真结果。试验结果表明：和未编码结构相比，当系统谱效率为4bit／（S·Hz^-1）时，采用该检测方法的编码系统有大约11．5dB的增益；谱效率为8bit／（S·Hz^-1）时，系统增益约为8dB。

英文摘要：

Recently, a particle filtering（PF） has been used as a hard detection of the Bell Laboratories Layered Space-Time （BLAST） scheme. The equivalent whitening filter output （WFO） model of the BLAST scheme was introduced, and a corresponding dynamic state space model （DSSM） was formed. Then, a soft particle filtering detection, stochastic, M algorithm, for BLAST scheme was achieved with the help of the DSSM. Finally, by applying the soft detection to the Turbo-MIMO system some stimulation results were obtained. The results demonstrate that this system provides a gain of 11.5 dB when the spectral efficiency is 4 bit（S · Hz^-1 ）, while approximately 8 dB when the spectral efficiency is 8 bit（S · Hz^-1 ）compared with the uncoded system.
