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.
ALG023
- NEWTON-RAPHSON求解一个连续方程,f(X)=0,前提给一个初始值- NEWTON-RAPHSON ALGORITHM 2.3 To find a solution to f(x) = 0 given an initial approximation p0: INPUT: initial approximation p0 tolerance TOL maximum n
fixed_point
- Fixed-Point iteration-Function fixed_point(p0, N) approximates the solution of an equation f(x) = 0, rewritten in the form x = g(x), which is a sub-function the user has to enter. the call to the function fixed_point(p0, N) returns the root of the eq
