执行自适应滤波器

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)

In this session, I will focus on the gridding method for fast image reconstruction from non- Cartesian data [1-5]. While gridding is not the only game in town, it is the reconstruction of choice when reconstruction time is an issue. Other reconstruction techniques include rBURS [6] and non-Cartesian iterative methods [7,8]. Non-Cartesian iterative methods generally use gridding and inverse gridding as their core operation, so even when gridding is not the right solution for an application, an understanding of gridding can be useful. I will cover the main steps of the gridding algorithm and then discuss some implementation tips that can signicantly reduce the computation time. Finally, I will present some illustrations and viewpoints that I have found to aid in an intuitive understanding of the gridding method, which can be helpful when designing the density compensation function and judging the appropriateness of gridding as a solution for a particular application.
