本程序是关于卫星上下变频的简单的实现算法，首先产生双边带调制信号，与收本振混频后，通过低通滤波器完成下变频。再与发本振混频，通过高通滤波器后完成上变频(This program is a simple algorithm on the satellite and down-conversion, the first double-sideband modulation signal generated, after the close of the oscillator mixer, low-pass filter complete the conversion. Again and send the local oscillator mixer, followed by the completion of the high-pass filter frequency)

In this paper, we present two novel class-based
weighting methods for the Euclidean nearest neighbor algorithm
and compare them with global weighting methods
considering empirical results on a widely accepted time series
classification benchmark dataset. Our methods provide
higher accuracy than every global weighting in nearly half
of the cases and they have better overall performance. We
conclude that class-based weighting has great potential for
improving time series classification accuracy and it might be
extended to use with other distance functions than the Euclidean
distance.

直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。(irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high rate of spread spectrum sequence extension in signal spectrum, and at the receiving end with the same spread spectrum code sequence for expansion, the expansion of the spread spectrum signal back into the original signal. )
