A MIMO multiplexing system with NT transmit and NR = NT receive antennas is designed.
The main challenge for MIMO systems lies in the non-orthogonality of the transmission channel.
This can be solved by turbo processing.
Turbo channel encoder is used for converting the bits in its suitable form.
Then different M-ary QAM is compared.

1. 按照式计算相似性矩阵
2. 排除自身的相似度
3. 按照式计算归一化矩阵
4. 按照式计算归一化拉普拉斯图矩阵L
5. 计算L的特征向量，将前个特征值最大的向量按列放置成一个矩阵，即依次为前个特征值最大的特征向量
6. 归一化X形成矩阵Y
7. 对矩阵Y按每行为一个数据点，进行k-means聚类，第行所属的类就是原来所属的类。(1. similarity matrix based on formula computation
2. rule out your own similarity.
3. normalized matrix based on formula computation
4. normalized formula Laplasse matrix L according to formula.
5. Calculate the eigenvectors of L. Place the vectors with the largest eigenvalues in columns into a matrix, that is, the eigenvectors with the largest eigenvalues in turn.
6. normalized X formation matrix Y
7. K-means clustering is applied to matrix Y according to one data point per behavior. The first row belongs to the original class.)
