首先根据短训练字的特性进行相关运算,进行信号到达检测,当检测到相关值大于门限一定次数后,认为有信号到达。然后根据长训练字的特性,进行相关运算,进行OFDM符号FFT窗口起始位置的估计。估计出FFT窗口的位置后,先在时域进行小频偏的估计,将两个长训练字进行小频偏补偿后,进行FFT运算,根据FFT运算的结果进行整数倍频偏的估计。这些参数估计完成后,就可以进行数据解调了。先对数据部分进行完整的频偏补偿,然后根据估计的FFT窗口位置进行FFT运算得到频域的数据,进行解调。然后在对应于导频的子载波位置上提

由于测量矩阵和方位噪声之间的相关性,我们已知的发射极定位的线性最小二乘算法,如伪线性估计器,具有较大的估计偏差。本文提出了一种新的基于闭型的发射器定位算法,该算法克服了这种偏倚,利用了比定位估计的辅助变量。通过计算机模拟,新算法的性能优于伪线性估计器,同时具有与计算成本更高的极大似然发射器相同的性能。(Because of the correlation between the measurement matrix and azimuth noise, we have known that th
