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) .)

说明：  从小数据量计算最大李氏指数的一种实用方法。(data from the largest Lyapunov exponent is calculated as a practical method.)

This Matlab source code is for paper PEGASIS for wireless sensor networks.

It works very well in Matlab and is very efficient

说明：  P.S.O相关源代码，对PSO初学者有较好的示例作用。(PSO-related source code, the PSO has a good example of the role of novice.)
