可实现QAM的星座图输出，仿真波形图输出，功率谱密度输出(Can be achieved QAM constellation diagram of the output, simulation waveform output, power spectral density output)

This code is calculating K-means in matlab programming.

Matlab code to study the decorrelation and energy packing efficiency of three transform techniques: Karhunen-Loève transform (KLT), discrete-cosine transform (DCT), and Walsh-Hadamard transform (WHT). Using a given vector of signal samples, it transforms the signal vector, quantize the transformed samples, and reconstruct the signal samples from the quantized samples
