SignCorrectionInSVDandPCA
虽然奇异值分解(SVD)和特征值分解(EVD的)是行之有效的,可以通过先进的设施设备先进的算法,它不是通常所说,有一个内在的迹象,可以显着影响的不确定性的结论计算及诠释来自其结果。我们提供一个解决方案,标志模糊的问题确定了从奇异向量的内积和个人数据载体签署奇异向量的迹象。该数据可能有不同的载体,但它有它自身的定位和实际意义的选择方向,其中多数的向量点。这可以通过评估发现了内心的签署标志产品的总和。(Although the Singular Value Decomposition (SVD) and eigenvalue decomposition (EVD) are well-established and can be computed via state-of-the-art algorithms, it is not commonly mentioned that there is an intrinsic sign indeterminacy that can significantly impact the conclusions and interpretations drawn from their results. We provide a solution to the sign ambiguity problem by determining the sign of the singular vector from the sign of the inner product of the singular vector and the individual data vectors. The data vectors may have different orientation but it makes intuitive as well as practical sense to choose the direction in which the majority of the vectors point. This can be found by assessing the sign of the sum of the signed inner products. )

FSK
数字频带通信系统
输入:首先输入模拟信号,给出此模拟信号的时域波形。
数字化:将模拟信号进行数字化,得到数字信号,可以选择PCM编码。
调制:可以选择简单的二进制数字调制方式。例如振幅键控(2ASK)、相移监控(2PSK)、频移键控(2FSK)、差分相移键控(DPSK)等。要求每个题目至少选择两种调制方式。有能力的同学也可以选择其它高效的调制方式?例如多进制数字振幅键控等?给出调制后信号的时域波形。
信道:假定信道属于加性高斯信道?或自行设计。
解调:相应的2ASK、2PSK、2FSK、DPSK解调,仿真获得解调输出波形。
PCM解码:给出解码后的模拟信号的时域波形,并与输入信号进行比较。
系统性能分析:比较在不同调制方式下,该数字频带传输系统的性能指标,即该系统的输出误码率随输入信噪比的变化曲线。(Digital frequency band communication system)
