EXIT
本源码包参考英国Southampton大学Robert G. Maunder教授2008年的EXIT charts开源demo，给出了通用(分量码多项式可自定义)并行级联Turbo码的EXIT charts的作图源码。同时可完成迭代轨线、BER等值线的绘制等工作。
由于对于码块长较大的情形仿真需要较长时间，源码包也给出了部分分量码多项式的仿真结果，可直接用于绘图。
源码包还给出了最经典的S.Ten Brink介绍EXIT charts基本原理的参考文献，以及本人对通信系统中迭代译码过程分析技术综述的小论文，希望对大家有所帮助。(This source package comes after Professor Robert G. Maunder s open source demo about EXIT charts in 2008 from University Southampton, UK. It is designed for universal (constituent code generation polynomial can be customized) Parallel
Concatenated Turbo Code EXIT charts. The iterative trajectories and BER contour drawing is also completed in this package. Since the long block case costs a lot of simulation time, some simulation results are included in the package. We also give the most classical introduction to the basic principles of EXIT charts from S. Ten Brink, as well as a document about analysis technologies for iterative decoding process in communication systems. Hope this will help.)

CPFSK
该工程是有关CPFSK（连续相位调制）的完整工程。帧结构包含训练序列、前导码、同步码、数据长度等信息，使用正交调制方式产生CPFSK的信号，生成基带IQ数据。接收端包含帧同步、滤波、解算长度等算法。可实现任意长度字符串的无线发送与接收。工程十分完整喝强大，可直接用于各大SDR平台的验证。(The project is a complete project of CPFSK (continuous phase modulation). The frame structure contains training sequence, preamble, synchronization code, data length and other information, and uses orthogonal modulation to generate CPFSK signals and generate baseband IQ data. The receiver includes algorithms such as frame synchronization, filtering, and calculating length. It can realize wireless sending and receiving strings of arbitrary length. The project is complete and powerful, and can be directly applied to the verification of major SDR platforms.)

ADIBEAM
ADIBEAM
Abstract—the increase in navigation accuracy demanded by
EGNOS and Galileo and their future evolution encourages the
study and design of advance receiver architectures. In that
direction, the ADIBEAM project focuses on the design of high
accuracy ground stations, specifically GNSS Reference Stations, in
order to improve its robustness in front of multipath and
interference errors with the goal of achieving centimeter level
tracking accuracy. The adoption of antenna arrays and digital
beamforming at the ground reference station receivers is one of
the most promising approaches to cope with errors induced by
multipath and interference.
