After the analytic model is set up and the error rate is derived, the system error performances of uncoded and Turbo coded DPIM are simulated and analyzed under weak turbulence channel, and the system error performances under Gaussian channel are simulated for comparison.

在建立分析模型和推导差错率的基础上，在弱湍流信道条件下仿真分析了Turbo码编码前后的系统差错性能，同时与高斯信道条件下的系统差错性能进行了比较。

The volcanic rocks of the Xiong'er Group is also widespread in the Baoji and Lvliang area and also appear as 1.75Ga-old mafic dyke swarms, A-type granites, later anorthosite and rapakivi granites (1.75-1.70Ga), and alkaline granitoids (~1.65Ga). These intrusive rocks are assumed to have genetic link to the volcanic rocks of the Xiong'er Group.
