QPSK调制 经典，非常简洁的产生qpsk的调制方法1(QPSK Modulation)

This file is a PV array model at different irradiations. It models a PV array which is a combination of different PV modules.

对原始码元序列进行基带成型，采用的是根升余弦滚降滤波器，可以更改参数变成升余弦滚降滤波器(Baseband shaping the source sequence, using root raised cosine roll-off filter, you can change the parameters into a raised cosine roll-off filter)

说明：  数学建模大赛常用的建模模型，对全国建模大赛很有帮助的啊！(Modeling Mathematical Modeling Contest common model of the national modeling contest helpful ah!)

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.
