说明：  《MATLAB 7.0从入门到精通》一书的配套程序——第3章的程序。()

Regulated DC Voltages simulink

说明：  认知无线电技术的提出是为提高频谱利用率，而认知无线实现的关键技术是频谱感知，众所周知协作检测提高了衰落环境中认知用户系统检测的性能，该文章是基于协作检测提出新的检测方案，利用了双门限方法提高了系统性能，兼顾带宽有限和增强性能两个方面，是基于门限检测的协作检测性能优化的前提。对以后门限优化协作检测非常有用。(In this paper, we employ a double threshold method in energy detector to perform spectrum sensing, while a fusion center in the cognitive radio network collects the local decisions and observational values of the secondary users, and then makes the final decision to determine whether the primary user is absence or not. Simulation results will show that the spectrum sensing performance channels is improved significantly under the proposed scheme as opposed to the conventional method.)

说明：  有详细的粒子群优化算法源代码，可以用于控制器参数寻优(Detailed particle swarm optimization algorithm source code, can be used for controller parameters optimization)

化学工业出版社出版的《MATLAB 从入门到精通》源代码(MATLAB book source codes.)

复调制的FFT变换，即ZOOMFFT，以及ZOOMFFT和FFT本质的注释，调试过，肯定没问题，希望对大家有帮助(FFT transform complex modulation that ZOOMFFT, as well as the nature of the comments ZOOMFFT and FFT, debug, certainly no problem, we want to help)

产生、播放DTMF音频，基于Goertzel算法估计DTMF音频，完成双音多频(DTMF)信号的检测(Generating, playing DTMF tones, DTMF tones based on the estimated Goertzel algorithm to detect the completion of dual tone multi-frequency (DTMF) signal)

同步变化的学习因子的粒子群算法，学习因子不为固定的常数(LnCPSO)

说明：  这些程序都是经过本人和许许多多工作过学习过的老师同学，以及一些志同道合的哥么们长期使用验证确实好使的(these procedures are numerous and I worked and studied the teachers and fellow students, and some like-minded Columbia Mody have long-term use of the test so that really)

主要描述了matlab中拟合与插值的方法，用插值法来应对实验数据不足的情况。(the code is mainly about the interpolation and fitting.If you don t have enough interpolation, you can use it.)
