Fuzzyclustering
模糊聚类;涉及事物之间的模糊界限时按一定要求对事物进行分类的数学方法。聚类分析是数理统计中的一种多元分析方法,它是用数学方法定量地确定样本的亲疏关系,从而客观地划分类型。事物之间的界限,有些是确切的,有些则是模糊的。例如人群中的面貌相像程度之间的界限是模糊的,天气阴、晴之间的界限也是模糊的。当聚类涉及事物之间的模糊界限时,需运用模糊聚类分析方法。模糊聚类分析广泛应用在气象预报、地质、农业、林业等方面。通常把被聚类的事物称为样本,将被聚类的一组事物称为样本集。模糊聚类分析有两种基本方法:系统聚类法和逐步聚类法。

OFDM Simulator

MIMO OFDM Simulator:
OFDM.m: OFDM Simulator (outer function)
create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile.
svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes.
BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance.
ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel).
chow_algo.m: Apply Chow s algorithm to generate a particular bit and energy allocation.
EnergyTableInit.m: Given the SNR values, form a table of energy increments for )
