Preamble-Based Channel Estimation for CP-OFDM and OFDMOQAM Systems A Comparative Study

本书描述了4G LTE / 5G NR 无线接入技术。(This book describes LTE, developed in 3GPP and providing true fourth-generation (4G) broadband mobile access, as well as the new radio-access technology 3GPP is currently working on. Together, these two technologies will provide 5G wireless access.)

SeaSon from DB-LAB of HIT 介绍的方法是以在cygwin中安装gdb为例说明。(SeaSon from DB-LAB of HIT is based on the method described to install gdb on cygwin an example.)

说明：  matlab卷积码编译程序，有详细的中文注释，希望对你有所帮助。(Matlab convolutional code compiler, the Chinese have detailed notes, and I hope to help you.)

采用卡尔曼滤波器对系统的俯仰角、 滚转角和航向角的误差进行最优估计；设计数据融合的判别准则，并根据判据的判断结果调整卡尔曼 滤波器中的量测信息，使系统可用于小型无人机的定高自主飞行(Kalman filter system pitch angle, roll angle and yaw angle error optimal estimation design data fusion criterion, and adjust according to the criterion of judging the results of measurement in the Kalman filter, making the system set high for small UAVs autonomous flight)

主要 对无线定位TDOA CHAN算法以及TAYLOR算法进行误码仿真并且仿真了一种两算法相结合的算法 并对误码进行比较(The content is mainly to simulate Chan Algorithm and Taylor Algorithm ,then compare their error performance.Based on them,A new Algorithm combining the two type of Algorithm is also proposed.)

PMA规约模拟测试软件。适合初学者使用，包含几个常用规约(PMA Statute of the simulation test software)

说明：  基于quartus的布斯乘法器的verilog 实现。布斯乘法算法是计算机中一种利用数的2的补码形式来计算乘法的算法。该算法由安德鲁·唐纳德·布斯于1950 年发明，当时他在伦敦大学伯克贝克学院做晶体学研究。布斯曾使用过台式计算器，由于用这种计算器来做移位计算比加法快，他发明了该算法来加快计算速度。(The verilog codes of booth multiplier based on quartus. Booth multiplication algorithm is a computer algorithm using the complement form of number 2 to calculate the multiplication. The algorithm was invented in 1950 by Andrew Donald booth, who was working on crystallography at birkbeck college, university of London. Booth used a desktop calculator, and because it was faster to do shifts than to add, he invented the algorithm to speed up the calculations.)
