代码说明:

matlab实现二级小波分解的图像压缩,用bior3.7小波基实现2层小波变换后,再利用matlab自带的函数wcodemat实现第一层和第二层图像压缩,并求取图像压缩前后的压缩比,均方差,峰值信噪比

  • 基于随机波束形成的多
    针对基于随机波束成形的多用户MIMO下行系统提出了三种调度算法:后端比例公平门限调度算法,后端最大值调度算法和后端比例公平最大值调度算法。通过仿真表明,这三种算法相比其他调度算法,在基本保持系统性能的前提下,能够降低反馈率,且有各自的特点和适用性:后端比例公平门限调度算法随着小区内用户数目的增多,反馈率越小,适合用户数较多的情况;后端最大值调度算法和后端比例公平最大值算法在用户数目较多的情况下,系统性能基本保持不变,且随着子信道数目增加,反馈率越小,适合天线数和用户数都较多的情况。-Based on random beamforming for multi-user MIMO downlink system proposed three kinds of scheduling algorithms: back-end proportional fairness scheduling algorithm threshold, the maximum back-end and back-end proportional fairness scheduling algorithm for the maximum scheduling algorithms. The simulation showed that the three kinds of algorithms compared with other scheduling algorithms, the basic premise of maintaining system performance, can reduce the feedback rate, and have their own characteristics and applicability: the back-end proportional fairness scheduling algorithm with the threshold number of users within a cell increases, the smaller the response rate for the number of users are more situation back-end and back-end ratio of the maxi
