说明: 为了提高认知无线电中感知用户对授权用户(主用户) 的检测概率,提出一种新的基于循环
谱统计量的主用户信号检测算法. 该算法利用循环谱离散频域平滑方法,对信号的循环谱在循环频
率处建立合理的检测统计量,然后求解得到对应不同虚警概率的判决门限,以使感知用户能检测信
噪比更低的授权用户信号.(To increase the detection probability of sensing users for licenced users (primary signals) in
the cognitive radio , it put s forward a new primary users signal method based on cyclic spect rum statis2
tics. By using discrete f requency smoothing of cyclic spect rum , this algorithm establishes the reason2
able detection statistics on the cyclic f requency of signal cyclic spect rum , then solves and obtains the
decision threshold correspond to different false alarm probability , as a result , making the sensing users
can detect licenced users signal under lower signal in noise ratio (SNR) .)

shelving
此功能会产生这是一个“搁置”的设计为一个单一的IIR双二阶系数。 wierldy不够,这种过滤器的类型是不标准的Matlab的滤波器设计工具箱的一部分。这些是常用的过滤器是创建一个图形均衡器的音频信号处理。(This function will generate the coefficients for a single IIR biquad that is a "shelving" design. Wierldy enough, this filter type is not part of the standard Matlab filter design toolbox. These filters are commonly used is audio signal processing to create a graphic equalizer.

FFT
1.用Matlab产生正弦波,矩形波,以及白噪声信号,并显示各自时域波形图
2.进行FFT变换,显示各自频谱图,其中采样率,频率、数据长度自选
3.做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱
4.用IFFT傅立叶反变换恢复信号,并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display
2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data
3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map
4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)
