Gradient Adaptive Laguerre Lattice Filter( Description： Implements the order recursive adaptive laguerre filter from Fejzo and Lev-Ari (1997). Advantages: *Fewer parameter to model than FIR filters modeling long impulse responses *guaranteed stability, unique global minimum, small number of parameter for prescribed modelling error *numerically robust & and low computational complexity ( O(M) ). *Fast convergence (RLS equivalent) with no apriori learning rate required *Order recursive, so filter coefficients are uncorrelated with each other, allowing for modular implementation. Setting the pole parameter to 0 yields the standard classical gradient adaptive FIR algorithm. Includes simple example on cross-talk resistant echo cancellation to show how to use it. )

Turbo decoder under awgn channel. (The input is: uncoded bits,coded bits 1,coded bits2(interleaved), LLR from other source(if use only one turbo code ,fill all zero is ok), numbers of iterations, interleaver between two CC, source bit,decoder id(if used in parreled connected turbo codes), interleaver between two sources(under the situation of two turbo codes).)

说明：  决定性系统中，设计一个状态观测器和反馈系统(Design a combined state observer and feedback system for the system below)

说明：  模型中明显地体现出模型设计主要有电流调节器和转速调节器两个负反馈闭环组成， 把转速调节器的输出当成电流调节器的输入，在通过电流调节器的输出控制后面的电路。 在这里电流环为内环，电压环为外环，所以形成了转速电流双闭环控制的直流调速系统。(The model obviously shows that the design of the model mainly consists of two negative feedback loops: current regulator and speed regulator, Take the output of the speed regulator as the input of the current regulator, and control the circuit behind it through the output of the current regulator. Here, the current loop is the inner loop and the voltage loop is the outer loop, so a DC speed regulation system with speed current double closed loop control is formed.)

高阶统计量目前应用越来越广泛，它比现在的一般统计量更能反应信号的特征，具有很好的应用前景。(Order statistics used widely at present, it is the general statistics than it is now more characteristic response signals, with good prospects.)
