说明： we shed light on the
potential and implementation of index modulation (IM) techniques for MIMO and multi-carrier communications
systems which are expected to be two of the key technologies for 5G systems. Specifically, we focus on two
promising applications of IM: spatial modulation (SM) and orthogonal frequency division multiplexing with IM
(OFDM-IM), and we discuss the recent advances and future research directions in IM technologies towards spectral
and energy-efficient 5G wireless networks.

gabor.rar
该代码仅计算了一个101×101尺寸的Gabor函数变换，得到均值和方差。代码采用两种卷积计算方式，从结果中可以看出，快速傅立叶变换卷积的效率是离散二维叠加和卷积的近50倍。
(The code is only the calculation of a 101 × 101 size Gabor function transformation, the mean and variance. Convolutional code using two methods of calculation can be seen from the results, fast Fourier transform convolution efficiency are two-dimensional discrete convolution superposition and nearly 50 times.)

NCestimation_V2
The NCT includes 4 External validity indices and 8 internal validity indices, and the sub-routine validity_Index.m is designed to use them.
This tool is suitable for the research work such as the performance comparison of different indices on estimation of the number of clusters, algorithm design by improving part codes of this toolbox.
i) External validity indices when true class labels are known:
Rand index
Adjusted Rand index
Mirkin index
Hubert index
ii) Internal validity indices when true class labels are unknown:
Silhouette
Davies-Bouldin
Calinski-Harabasz
Krzanowski-Lai
Hartigan
weighted inter- to intra-cluster ratio
Homogeneity
Separation
iii) Others
Error rate (compared with true labels)
System Evolution: it is used to estimate the number of clusters and give separable degrees between clusters.
