MU-MIMO-technique
文档中介绍首先介绍了多用户MIMO模型,以及LTE中的多用户MIMO方案,通过仿真分析总结出当用户数较少时,在高信噪比条件下,ZF方案的系统吞吐量性能明显优于PU2RC方案。(Document describes first introduced a model of a multi-user MIMO, and LTE multi-user MIMO scheme, by simulation analysis summed up when the number of users is small, at high SNR conditions, the system throughput performance of the ZF program superior PU2RC program.)

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)

mimo_ofdm_slm
In this paper, we present a Selected Mapping (SLM) PAPR reduction technique for MIMOOFDM
system with special protection of Side Information (SI). Selected Mapping (SLM)
is a powerful PAPR reduction technique since it does not cause any signal distortion and
simple to implement. As a special protection for the Side Information (SI) of SLM technique,
we propose a SI power allocation procedure. Simulation results show that our proposed
technique gives significantly better BER performance than the ordinary SLM technique for
MIMO-OFDM systems. Analysis for the optimum SI power allocation is also presented.
