基础的PSO算法

vector controle of the induction machine

实验要求：在一张图上绘制三种二进制信号（即反极性信号、开关信号和正交信号）的误码率。这三种信号可以在几何上用“信号空间”中的点来表示。在反极性信号情况下，信号是±s(t)，每个都有能量E。开关信号也是一维信号，所以两个信号为0和s(t)，正交信号我们上课已讲过。要求信噪比为0：12dB。(Experimental requirements: to draw a diagram of three binary signals (i.e., reverse polarity signal, the switching signal and quadrature signal) BER. These three signals can be in the geometric point in the signal space. In the reverse polarity signal case, the signal is s (t), each have energy E. The switching signal is also a one-dimensional signal, so the two signals is 0 and s (t), the quadrature signals teach us have talked. Signal-to-noise ratio to 0:12 dB.)

粒子群优化算法(PSO)是一种进化计算技术(evolutionary computation)，有Eberhart博士和kennedy博士发明。源于对鸟群捕食的行为研究 PSO同遗传算法类似，是一种基于叠代的优化工具。系统初始化为一组随机解，通过叠代搜寻最优值。但是并没有遗传算法用的交叉(crossover)以及变异(mutation)。而是粒子在解空间追随最优的粒子进行搜索。详细的步骤以后的章节介绍 同遗传算法比较，PSO的优势在于简单容易实现并且没有许多参数需要调整。目前已广泛应用于函数优化，神经网络训练，模糊系统控制以及其他遗传算法的应用领域(Particle Swarm Optimization (PSO) is an evolutionary computation technique (evolutionary computation), has Dr. Eberhart and Dr. kennedy invention. Deriving from the behavior of birds of prey PSO with genetic algorithm is similar to an iterative optimization-based tools. System initialization for a group of random solutions, through the iterative search for optimal values. But there is no cross-genetic algorithm used (crossover) and mutation (mutation). But the particles in the solution space of the particles to follow the optimal search. In detail the steps after the introduction sections compared with the genetic algorithm, PSO has the advantage of being simple and easy and did not realize many of the parameters need to be adjusted. Has been widely applied to function optimization, neural network training, fuzzy system control, as well as other genetic algorithm applications)

In this simulink model , QPSK modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
