IT家园论坛通信仿真精华资料汇总，提供如MIMO信道的建模，误码率比较等的实际访深例子。-IT Forum home the essence of communication simulation data aggregation to provide, such as MIMO channel modeling, error rate comparison of the actual visit to the deep examples.

Data aggregation is essential that exploits correlated sensing data and aggregates at intermediate nodes to reduce the number of messages and to improve the energy efficiency in wireless sensor networks. This project considers the problem of construc

数据挖掘中, k-Means 算法是一种 cluster analysis 的算法,其主要是来计算数据聚集的算法,主要通过不断地取离种子点最近均值的算法。-In data mining, k- Means algorithm is a kind of cluster analysis algorithm, the main is to calculate the data aggregation algorithm, mainly through constantly take the seed

提出了一种细化FFT的短时傅立叶变换(shorttimeFouriertransform,简称STFT)时频分析新方法.STFT实 质为加窗的傅立叶变换,在窗内数据满足平稳性条件下利用傅立叶变换获得频谱,并依据时间间隔移动窗函数最终得到时频表示.细化FFT在分析频率范围内具有较高的频率分辨率,将细化FFT应用于STFT的窗内数据,可有效提高STFT的时频聚集性-Proposed a frequency analysis of short-time Fourier transform FFT re
