代码说明:

  利用MATLAB 仿真工具设计出一个QPSK仿真程序,以衡量QPSK在理想信道、高斯白噪声信道和先通过瑞利衰落信道再通过高斯信道三种方式的调制解调得到的功率谱密度、噪声曲线、星座图及误码性能,并对仿真结果进行了分析。(QPSK simulation design and Realization Based on MATLAB)

    说明:  :Mean—shift算法是一种非参数密度估计算法,可以实现快速的最优匹配,在目标的实时跟踪领域起着非常 重要的作用。为了有效的将Mean—shift算法应用到灰度图像中,采用了以方向直方图建立目标模型的策略,提出了在灰 度图像中以Mean—shift为核心的目标跟踪算法。实验结果表明,该算法具有不受光照条件影响的优点,在低对比度的情 况下仍能实现稳定、实时的跟踪目标。(: Mean-shift algorithm is a nonparametric density estimation algorithm, the optimal matching can be fast, real-time tracking fields in the target plays an important role. In order to effectively Mean-shift algorithm will be applied to the gray image, the histogram used to establish the direction of the strategy target model is proposed in the gray image to Mean-shift tracking algorithm as the core. Experimental results show that the algorithm has the advantage of not lighting conditions, in the case of low contrast can still achieve stability, real-time tracking of targets.)
