matlab编写的多元变量最小化问题的downhill方法求解(matlab prepared multi-variable minimization problem downhill method)

非线性曲线拟合使用maltab牛顿高斯迭代，并用初始值(Nonlinear curve fitting useing Maltab Newton gaussian iteration need Initial value )

用 LDPC 解码法，对原始信号通道的噪声进行评估，消去。具体原理可参照IEEE TCOM的论文。(Channel Noise Estimation or correlation estimation for distributed source coding Using Particle based Belief Propagation for LDPC decoding in AWGN and BSC models. This code is partially based on our published journal papers with some additional improvements. In this code, we removed the parameter lambda to reduce the number of free parameters. PBP estimator is distributed in the hope that is will be useful, but without any warranty. The codes have not been optimized, so the estimation speed may be slow. To use PBP estimator source code in your research, please cite our journal papers published in IEEE TCOM. )
