Combining its real geometrical structure, a polishing robot's error model is established and a single point method is used to identify the geometrical parameter errors.

本文首先结合某打磨机器人的实际几何结构，建立了该机器人的误差模型，利用单点法来辨识几何参数误差值；

Many single BP networks make up of predictive model paratactically, each predictive model can not be affected each other, so the error is not accumulate.

由多个单独BP 网以并行方式构成预测模型，各子预测模型间无直接影响，因此没有误差积累。

Then, the whitened dimension-reduced data vector as a single user model is looked, the Iterative Least Squares (ILS) detection and Minimum Mean Square Error (MMSE) detection are researched.

将白化滤波后的降维数据矢量看作是单用户的系统，研究了迭代最小二乘(ils)检测和最小均方误差(MMSE)检测。
