简单的OOK调制程序，很不错的哦，大家来吧！(Good OOK modulator program)

TD-LTE下行传输采用了MIMO-OFDM的物理层构架，通过最多4个发射天线并行传输多个（最多4个）数据流，能够有效地提高峰值传输速率。LTE的物理层处理过程中，预编码是其核心功能模块，物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by up to four more (up to 4) data flow, can effectively improve the peak transmission rate.LTE) in the process of the physical layer of precoding is its core function module, several kinds of main physical downlink Shared channel transmission model is achieved by precoding.)

说明：  基于matlab,通过MPPT控制实现光伏逆变(Based on matlab, realize photovoltaic inversion by MPPT control)

该工程实现对单载波系统QPSK的频偏估计算法。调相信号在接收机相干解调时需要同频同相的参考载波，而发射机和接收机之间往往存在频率偏差，为了消除这种误差，必须在软件层面实现。使用了QPSK四相调制的信号特点进行载波频偏估计，经验证，效果较好。(This project implements frequency offset estimation algorithm for single carrier system QPSK. The phase modulation signal needs the same frequency reference carrier in the coherent demodulation of the receiver, and the frequency deviation often exists between the transmitter and the receiver. In order to eliminate this error, it must be implemented on the software level. The carrier frequency offset estimation is carried out by using the signal characteristics of QPSK four phase modulation.)

空域滤波代码，对阵列信号处理，滤除不需要方向上的信号(Spatial filtering code, array signal processing, filtering do not need direction signal)

说明：  利用遗传算法的全局搜索能力，可以避免传统的多目标优化方法在优化过程中陷入局部最优解，保持解个体的多样性。(By using the global search ability of genetic algorithm, it can avoid the traditional multi-objective optimization method falling into the local optimal solution in the process of optimization, and keep the diversity of solution individuals.)

说明：  IEEE 14 bus 的连续潮流计算的MATLAB程序, 不错的参考代码。(Continuation power flow for IEEE 14 bus system)
