modulation
对现有数字调制方式识别类型有限的问题，提出一种基于星座图的分类算法。算法首先利用盲均衡技术克服信道的多径效应与系统问步误差，再对信号减法聚类，提取聚类中心与理想星座图模型进行匹配，从而实现MAsK、MPsK、MOAM等调制方式的识别。(Existing types of digital modulation recognition of limited problem, a classification algorithm based on the constellation. Firstly, the use of blind equalization technique to overcome the effects of multipath channel and ask-step system error, and then the signal subtraction clustering, cluster centers extracted constellation model and the ideal match to achieve MAsK, MPsK, such as modulation recognition MOAM.)

说明： 多目标货物配装问题是一个复杂的组合优化问题，属于NP难问题，本文用混合粒子群算法求解多目标货物配装问题。混合粒子群算法在基本粒子群算法的基础上，通过引进遗传算法中的交叉和变异的策略，避免了陷入局部最优，加快了达到全局最优的收敛速度。此外，本文提出用权重系数来平衡各目标使各目标都能达到相对较优的效果。(Multi-objective loading of goods is a complicated combinatorial optimization problems are NP hard problems, this paper, hybrid particle swarm algorithm to solve multi-objective problem loading cargo. Hybrid Particle Swarm Algorithm in elementary particle swarm optimization based on genetic algorithm through the introduction of crossover and mutation of the strategy to avoid a fall into local optimum, global optimum to achieve accelerated convergence. In addition, this paper, the weight factor used to balance the various objectives so that the objectives can be achieved relatively better results.)
