1、 极大似然估计
尝试用0~24阶多项式拟合,并用5折交叉验证选择最佳模型(多项式阶数及其系数,给出类似课件中的图),并画出最佳模型的拟合效果图(类似图1,蓝色点为训练样本、红色点为测试样本、绿色线为模型预测),给出该模型的测试误差。
2、 岭回归
多项式阶数为24,正则系数λ的取值范围为exp(-19)到exp(20),采用并用5折交叉验证选择最佳模型。实验结果要求同1。

研究无线信道优化问题, 由于非确定性 M MIO系统的信道矩阵行不满秩特性, 导致 MM SE- GDFE左预处理后引入了强干扰, 使得传统 K- Best算法产生了误码平层效应。为了消除误码平层效应,提出部分最大似然和 K - Best结合算法, 并在初始检测的强干扰区域利用部分最大似然算法获得局部最优解, 降低强干扰对系统的影响消除误码平层效应, 进而在局部最优解的基础上利用 K- Best算法完成剩余符号的检测, 保证 M MIO 检测器的软输出特性。仿真结果表明算法消除了传统 K- Be
