K-means

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.

说明：  首先确定被评价对象的因素（指标）集和评价（等级）集；再分别确定各个因素的权重及它们的隶属度向量，获得模糊评判矩阵；最后把模糊评判矩阵与因素的权向量进行模糊运算并进行归一化，得到模糊综合评价结果(Firstly, the factor (index) set and the evaluation (grade) set of the evaluated object are determined; then the weight of each factor and their membership degree vectors are determined separately, and the fuzzy evaluation matrix is obtained; finally, the fuzzy evaluation matrix and the weight vector of the factor are fuzzily calculated and normalized, and the result of the fuzzy comprehensive evaluation is obtained.)
