sir/mam, i have added some matlab source codes,in turn provide some required matlab source codes

用matlab构建的信号发生器，其中包括交互界面，产生各种简单的波形，以及波形的混合叠加，以及外加音频的简单处理。交互界面中可以清楚看到波形的时域和频域的波形，包括波形的幅值，周期，功率均有图形显示(Constructed using matlab signal generator, including interface, simple treatment produces a variety of simple waveforms, and mixed superimposed waveforms, as well as external audio. Interactive interface, you can clearly see the waveform frequency domain and time domain waveforms, including the waveform amplitude, period, power has a graphic display )

Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.

说明：  此为频偏校正程序,通过TD_GG算法得到的频偏值还存在几赫兹的残余频偏，这里，我们可以通过反馈算法进行校正，以得到更加精确的频偏值。(for this frequency offset correction procedure for the adoption of the algorithm TD_GG Frequency values still exist remnants of a few hertz frequency offset, here, we can pass feedback correction algorithm, to be more precise frequency offset value.)
