fuzzy_control
用MATLAB编写的离散模糊控制程序,结合本程序,我相信能能更快更好的理解模糊控制算法。算法在MATLAB Version: 7.14.0.739 (R2012a)运行无误。
function [FCU_T1,FCU_T2,FCU_T3,FCU_T4]=fuzzy_table(Me,Mec,Mu,UC)
Me 隶属度表1
Mec 隶属度表2
Mu 隶属度表3
UC 模糊规则
FCU_T1 重心加权法,输出精确值
FCU_T2 重心加权法,输出离散值
FCU_T3 重心加权法(对隶属度平方),输出离散值
FCU_T4 最大隶属度法
function [R,n,nE,nEC,nU,nfe,nfec,nfu]=fuzzy_relation(Me,Mec,Mu,UC)
Me 隶属度表1
Mec 隶属度表2
Mu 隶属度表3
UC 模糊规则
R 表示全体规则构成的模糊关系
n=nfe×nfec
nE 模糊变量E的语言值个数
nEC 表示模糊变量EC的语言值个数
nU 表示模糊变量U的语言值个数
nfe 表示E的等级量个数,示例1中其论域为{-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6}
nfec 表示EC的等级量个数,示例1中其论域为{-6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6}
nfu 表示U的等级量个数,示例1中其论域为{-7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7}
Me 表示E的隶属度表
Mec 表示EC的隶属度表
Mu表示U的隶属度表
UC表示规则表(fuzzy control algorithm(matlab program))

ofdm-siso
正交频分复用是一种多载波宽带数字调制技术。相比一般的数字通信系统,
它具有频带利用率高和抗多径干扰能力强等优点,因而适合于高速率的无线通信系统。(
OFDM Simulator
--------------------------------------------------------------------------------
MIMO OFDM Simulator:
OFDM.m: OFDM Simulator (outer function)
create_channel.m: Generates a Rayleigh fading frequency-selective channel, parametrized by the antenna configuration, the OFDM configuration, and the power-delay profile.
svd_decompose_channel.m: Since full channel knowledge is assumed, transmission is across parallel singular value modes. This function decomposes the channel into these modes.
BitLoad.m: Apply the bit-loading algorithm to achieve the desired bit and energy allocation for the current channel instance.
ComputeSNR.m: Given the subcarrier gains, this simple function generates the SNR values of each channel (each singular value on each tone is a separate channel).
chow_algo.m: Apply Chow s algorithm to generate a particular bit and energy allocation.
EnergyTableInit.m: Given the SNR values, form a table of energy increments for )

sdafsearchbnd
Fminsearch不承认的约束限制。
不过简单的转换方法存在
转换成一个绑定的约束问题
无约束问题。
Fminsearchbnd用于酷似fminsearch,
除了边界应用到变量。
应用于国内的界限,利用
改造中的变量。 (二次型
单式,双罪恶界(十)。)
具有包容性的不平等的界限,它承认
边界值本身,但不准
在所有函数之外的范围评估。
请注意,fminsearchbnd允许用户准确地固定在某个给定值通过设置一个变量的确切范围相同的值。(Fminsearch does not admit bound constraints.
However simple transformation methods exist to
convert a bound constrained problem into an
unconstrained problem.
Fminsearchbnd is used exactly like fminsearch,
except that bounds are applied to the variables.
The bounds are applied internally, using a
transformation of the variables. (Quadratic for
single bounds, sin(x) for dual bounds.)
The bounds are inclusive inequalities, which admit
the boundary values themselves, but will not permit
ANY function evaluations outside the bounds.
Note that fminsearchbnd allows the user to exactly fix a variable at some given value, by setting both bounds to the exact same value.)
