matlab仿真，有关纠错码中卷积码的性能仿真，1/N速率的(matlab simulation, the error-correcting codes in the convolutional code performance simulation, 1/N rate)

用于进行eeg独立分量分析的多个函数，可以直接调用(EEG used for a number of independent component analysis function, can directly call)

UKF Unscent Kalman Filter 算法(Unscent Kalman Filter)

main函数调用的子函数均可以随意修改,使用方便 模块包括：流程控制模块、卷积编译码模块、交织解交织模块、调制解调模块、OFDM调制解调模块、信道模块(为多径rayleigh信道)、均衡模块 可以正常运行,绝对适合做OFDM研究使用,有详细的注释,我自己写的,很容易理解. 经典收藏!! (The main function calls the subfunctions are free to modify, easy to use modules including: flow control module, convolution encoding and decoding module, interleaving solution intertwined module modem modules, the OFDM modem module, channel module (multipath rayleigh channel ), equalization module can operate normally, absolutely suitable for OFDM study used detailed notes, I wrote it myself, it is easy to understand. classic collection!)

绘制莱斯分布，本程序简单明了，并且可以修改参数(Draw Rice distribution, this procedure is simple, and you can modify the parameters)

传统的近似三角形内点测试( APIT),即近似三角形内点测试定位算法,广泛应用于静态节点定位.结合粒子滤波提出改进算法,将APIT算法推广到节点动态定位.(Traditional approximate point inside the triangle test (APIT), namely the approximate point within the triangle test positioning algorithm, widely used in the static node localization. Combined with particle filter algorithm is proposed to improve the APIT algorithm is extended to the node dynamic positioning.)

实现产生伪随机序列的部件 —— 线性反馈移位寄存器单元。 SFlog2为扩频因子的底数为2的对数值，cycle为PN序列的周期，其值为2^SFlog2。initial_state为移位寄存器的初始状态，generator_polynomial_coefficient为生成PN序列所需的本原多项式，对应于移位寄存器的连接向量。(The realization of pseudo-random sequence generated components- LFSR unit. SFlog2 factor for the spread-spectrum base 2 of value, cycle for the PN sequence cycle, its value is 2 ^ SFlog2. initial_state shift register for the initial state, generator_polynomial_coefficient to generate the necessary PN sequence primitive polynomial, corresponding to the shift register connection vector.)
