Two-dimensional angle/delay and polarization parameter separable estimation for TDD CDMA systems

在研究一维角度、时延和极化联合估计(JADPE)方法基础上,提出一种多径信道下的二维角度、时延和极化参数联合估计方法。该方法将极化敏感阵列天线和TDD CDMA系统结合起来,研究了TDD CDMA系统多用户、多径情况下联合参数估计问题,有效实现了TDD CDMA系统二维角度/时延/极化参数的高分辨联合估计。该方法通过引入极化敏感阵列提高了信道参数估计的精度,适用于TDMA系统和TDD CDMA系统,联合参数可有效地实现三维定位。仿真结果证明了算法的有效性。
