基于非线性能量算子的信号解调MATLAB实现(Nonlinear energy operator based signal demodulation realize MATLAB)

in this projeh DVB-T signal can simulate by matlab

This matlab code describes soft demapper (soft bit) for different modulation types: BPSK, QPSK, PSK 8, QAM 16, QAM 64, which are considered for turbo encoding/decoding. And simulation results are also presented.

本书包含MATLAB使用和数学知识的丰富层次。编著本书有四个主要目的：（1） 帮助初学者顺利跨入MATLAB大门；（2） 全面、多层次、细致而深入地叙述MATLAB中数值、字符串、胞元、构架、逻辑、函数句柄六种重要数据类型的应用规则、相互配用和编程规范；（3） 由浅入深地阐述MATLAB三种建模、分析、仿真环境——数值计算、符号计算和Simulink环境的特征和使用要领；（4） 以实例讲述MATLAB代表的现代计算能力对传统算法和思维的影响。(Book contains rich levels of using MATLAB and mathematics knowledge. Compiled the book has four main purposes: (1) help beginners MATLAB entered the door smoothly (2) comprehensive, multi-level, meticulous and thorough account Numbers, strings, cell yuan, in the MATLAB framework, logic and function handles six important application rules, with each other and programming of the data type specifications (3) describes the MATLAB distinguished three kinds of modeling, analysis, simulation environment, numerical and symbolic computation and Simulink environment characteristics and use of the essentials (4) with examples about MATLAB on behalf of the modern computing power s influence on the traditional algorithm and thinking. )

人生路模拟人体结构 实现性别辨别，研究肌肉 速度 肩宽 对速度的影响(matlab WALKER Human gait. This model, developed by Nikolaus Troje, is a five-term Fourier series with vector-valued coefficients that are the principal components for data obtained in motion capture experiments involving subjects wearing reflective markers walking on a treadmill. The components, which are also known as "postures" or "eigenwalkers", correspond to the static position, forward motion, sideways sway, and two hopping/bouncing movements that differ in the phase relationship between the upper and lower portions of the body. The postures are also classified by gender. Sliders allow you to vary the amount that each component contributes to the overall motion. A slider setting greater than 1.0 overemphasizes the characteristic. Can you see whether positive values of the gender coefficient correspond to male or female subjects? )
