LHS
拉丁超立方抽样，调用方式如下：S=lhs(m,dist,mu,sigma,lowb,upb)
m: a scalar,the number of sample points
dist: A row with distribution type flags of basic random variables the
value of the flag can be 1 (for uniform distribution, 2(for normal distribution), 3(for lognormal)
and 4(for extreme type 1).
mu: A row vector comprising the mean value of basic random variables.
sigma: A row vector with its length equaligng to mu,including the standard
deviation of basic random variables.
lowb: a row vector with its elements are the lower bound of the sampling
interval
upb:a row vector with its elements are the upper bounds of the sampling
interval
dist,mu,sigma,lowb,upb must have the same length.
Output argument
S: sampling point matrix, of which each row is a sampling point.(code of Latin Hypercube Sampling)

LDPCBSN
LDPC码既低密度奇偶校验码（Low Density Parity Check Code，LDPC），它由Robert G.Gallager博士于1963年提出的一类具有稀疏校验矩阵的线性分组码，不仅有逼近Shannon限的良好性能，而且译码复杂度较低, 结构灵活，是近年信道编码领域的研究热点，目前已广泛应用于深空通信、光纤通信、卫星数字视频和音频广播等领域。LDPC码已成为第四代通信系统(4G)
(LDPC codes BER simulation under AWGN channel. MacKay-Neal based LDPC matrix. Message encoding uses sparse LU decomposition. There are 4 choices of decoder: hard-decision/bit-flip decoder, probability-domain SPA decoder, log-domain SPA decoder, and simplified log-domain SPA decoder.)

RS_coding
The Hamming codes (described in the previous section) are suitable for detecting random bit errors
in a sequence of transmitted bits. If the communication medium is prone to burst errors (channel
errors affecting contiguous blocks of bits), then the Hamming code may not be suitable.
Reed Solomon Codes are linear block codes, a subset of the BCH codes called non-binary BCH.
The (n, k) RS code contains k data symbols and n-k parity symbols. RS Codes are also cyclic codes
since the cyclic shift of any codeword will result in another valid RS codeword.
