IIR
使用matlab实现设计IIR滤波器：冲激不变法、双线性变换法
设计一个巴特沃思低通滤波器，其技术指标为：3dB带宽为，阻带截止频率为，阻带衰减大于30dB，采样间隔T=10us。
1）用冲激响应不变法
2）用双线性变换法设计
3）用FIR的矩形窗函数设计
二、用双线性变换法分别设计低通、高通、带通、带阻四种滤波器。模拟滤波器带原型分别为切比雪夫滤波器和椭圆滤波器，采样率Fs=20kHz，指标如下：
1）低通：通带0～4 kHz，阻带5 kHz，通带衰减Rp=0.5dB，阻带衰减As=10dB。
2）高通：阻带0～4 kHz，通带5 kHz，通带衰减Rp=0.5dB，阻带衰减As=10dB。
3）带通：通带2kHz～4 kHz，阻带0～1.5 kHz，4.5kHz以上，通带衰减Rp=0.5dB，阻带衰减As=10dB。
4）带阻：阻带2kHz～4 kHz，通带0～1.5 kHz，4.5kHz以上，通带衰减Rp=0.5dB，阻带衰减As=10dB。(Using MATLAB to implement the design of IIR filters: impulse invariant and bilinear transformation)

ECA_RD_DRM
说明： 产生复高斯的白噪声,这和matlab 自带的不一样，容易理解，但是经对比还是和自带的有区别的(AWGN noice we are very nice. please try to run it snd you will find you are good too.)

OFDM
利用MATLAB软件对OFDM系统做出仿真。仿真中采用QPSK调制技术，并加入高斯白噪声，最终得到QPSK星座映射图以及BER曲线图。由仿真结果可以看出，OFDM在高斯信道具有良好的抗噪声性能，误码率较低。(MATLAB software is used to simulate the OFDM system. In the simulation, QPSK modulation technology is used, and Gauss white noise is added, and the map of the QPSK constellation and the BER curve are finally obtained. It can be seen from the simulation results that OFDM has good anti noise performance and low error rate in Gauss channel.)

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.
