多频道奇异谱分析，即奇异谱分析的升级版，广泛应用于气象变化，股市波动，降噪等领域。(Multi-channel singular spectrum analysis, that singular spectrum analysis of an upgraded version of the widely used weather changes, stock market volatility, noise reduction and other areas.)

跳频（占空比为1）2fsk的部分频带干扰误码率计算，这个程序是基于matlab的，自己编的，呵呵(Frequency Hopping (duty cycle 1) 2fsk the partial band interference bit error rate, this procedure is based on matlab, and their series, Oh)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".
