matlab code for deec protocol

说明：  pso优化lssvm代码，用于回归预测等可以获得更好的效果(PSO optimizes the LSSVM code, which can be used for regression prediction to get better results)

M-QAM系统的调制和解调以及在噪声条件下的误码率性能分析(M-QAM-modulation-demodulation)

说明：  随机减量RDT法matlab程序，可用于提取信号中的自有衰减振动响应信号(Matlab random decrement process RDT method can be used to extract the signal attenuation of vibration signals of its own)

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)

channel equalizer for wireless communication system

说明：  自适应滤波器。自适应滤波器为11个权系数的FIR结构。（1）不同的方差σ2（2）LMS算法画出一次实验的误差平方收敛曲线，训练长度为500，给出滤波器系数；进行20次独立实验，给出平均收敛曲线。不同步长值的比较。（3）RLS算法，LMS和RLS算法的比较 (Adaptive filter. Adaptive filter weights for 11 of the FIR structure. (1) different variance σ2 (2) LMS algorithm for an experiment to draw square error convergence curve, the training length is 500, given filter coefficient conduct 20 independent experiments, given the average convergence curve. Are not synchronized long value comparison. (3) RLS algorithm, LMS and RLS Algorithms)

matlab的命令大全，很详细，对各个命令的解释很全面，附带有例子(matlab command Daquan, very detailed, very comprehensive explanation of each command, with the example of)

一种基于区域增长的图像分割方法，代码实现比较简单。(An image segmentation method based on regional growth, the code is relatively simple.)

ecent advances in electrical engineering and computer science, esp ecially in micro- electro-mechanical systems (MEMS), very-large-scale integration (VLSI) and op erating system theory, have made wireless sensor network (WSN) technologies an imp ortant and promising research area. As the circuitry b ecame smaller and cheap er, the idea of co op eratively sensing physical or environmental conditions, such as magnetic eld intensity, temp erature, light intensity, sound, vibration, pressure, motion or p ollutants with the help of a network of sensor no des has b ecome feasible.
