surface plot for matlab

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

针对C语言环境下的电力系统潮流计算过程中，负责数据输入的子程序。(Power flow calculation for the C language environment in the process, is responsible for routine data entry.)

包含了CMMB系统发端从星座映射开始直到完成OFDM调制的过程。(Contains the system originating from the constellation mapping CMMB start until the completion of OFDM modulation process.)

it s a matlab source code about funtional approximation for numerical methods

全桥移相的电路仿真及电路搭建，大家可以相互学习下。(Phase-shifted full-bridge circuit simulation and circuit structures, we can learn from each other the next.)

用于产生多相编码序列P1码以及对产生的码字进行匹配脉压(generate P1 code and let the code throngh the matched filter)

It is a useful book for manipulator robot, calculate inverse kinematic. A geometric approach in solving the inverse kinematics of puma robot. Including two main parts: Arm solution for first three joints and Arm solution for last three joints. For me, it s a good book.
