频率同步是MIMO-OFDM同步技术必须解决的问题之一,但是传统的基于ML算法的频率偏移估计条件要求苛刻,计算复杂,因此对CFO简单算法的探究势在必行。为此提出一种基于LS算法的频率偏移估计,并将其性能与基于ML的频率偏移估计的性能进行比较。仿真结果表明,LS算法性能等同于ML算法性能。基于LS算法的简单性和使用条件的低约束性,可使用LS算法获得和ML算法相同的频偏估计。

图3.9 恒虚警检测器原理框图
实际工作时，为了减少虚警点，选择二维恒虚警检测，先在距离维做滑窗处
理，完成距离维的恒虚警检测，如果检测单元超过门限，然后对这个检测单元再
做一次多普勒维的恒虚警检测。因为杂点有可能距离维过了门限，但是不满足多
普勒维的检测门限，经过两维检测之后可以减少杂点。又因为同一个目标信号有
可能在相邻的多普勒滤波器中都有输出，所以可以在每个距离单元上进行简单的
选大，如此，在一个距离单元上只对应一个多普勒频率值，使目标多普勒频率更
加精确。
