V-BLAST-simulation
比较采用干扰消除和无干扰消除的V-BLAST系统误帧率与SNR的关系曲线。系统参数：收发天线个数M=4，N=6；设定发送信号总功率P=1；设定每一帧中的符号数Nframe=100；调制方式为16QAM；信道为不相关瑞利衰落信道。(Was used to compare the interference canceller and V-BLAST system without interference cancellation, the frame error rate and SNR curve. System parameters: the number of transmit and receive antennas M = 4, N = 6 set to send the signal power P = 1 set the number of symbols in each frame Nframe = 100 modulation for 16QAM channel is not related to Rayleigh fading channel.)

Transmission-Model
无线传感器网络定位用到的无线传输模型
Regular Model, Logarithmic Attenuation Model, DOI Model, RIM Model
(Wireless sensor network localization using wireless transmission model, Regular Model, Logarithmic Attenuation Model, DOI Model, RIM Model
Achieve functional distance and transmission attenuation swap
~~~~~~~~~~~~~~~~~~~~~~Regular Model~~~~~~~~~~~~~~~
In this model, the radio range is a circle
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
ReceivedSignalStrength=SendingPower-PathLoss
e.g, RSS=Pt-Pl(d0)-10*η*log10(dist/d0)
Pt:transmit power
pl(d0):the pass loss for a reference distance of d0
ηis the path loss exponent
above parameters are saved in ../Parameters_Of_Models.mat
dist:distance between sender and receiver(m)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
typical value:Pt=0-4dBm(max),Pl(d0)=55dB(d0=1m),η(2~4)=4(indoor,outdoor)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~Logarithmic Attenuation Model~~~~~~~~~
In this model, the radio range is a circle
