matlab code for solve equation

An Artificial Neural Networks Lab

it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in this program multiuser CDMA system is used ,, spreading is done using HADAMARD matrix .. or WALSH code .. and BER vs SIGNAL to NOISE ratio graph is computed

时频分析方法提供了时间域与频率域的联合分布信息，清楚地描述了信号频率随时间变化的关系。(Time-frequency analysis method provides a time-domain and frequency domain, the joint distribution of information that clearly describes the signal frequency versus time relationships.)

说明：  有限元Matlab程序，两网格并行程序，Morley程序(Finite Element Matlab program, the two grid parallel program, Morley program)

一本matlab rune教材，有很多实例，比较简单，学习过程中可以不断尝试。(A book about matlab,it can be used by those who knows little about matlab.)

电机的各种启动方式，包括直接启动，串电阻启动，降压启动，还包括电机的制动方式(A variety of ways to start the motor, including direct start, series resistance started, the buck starts, including braking motor)

Genetic Algorithm for function maximization. Especially useful for functions with kinks and discontinuities, and where a good "starting point" is unavailable.

说明：  C’est avec un grand plaisir que je remercie M Fran&ccedil ois Costa, M Jean Luc Schanen et M Faouzi Ben Ammar qui ont accepté de faire partie de mon jury de thèse. Des remerciements aussi chaleureux vont à mes collègues du CEGELY avec qui j’ai partagé ces années de travail, je pense à tout(e)s les doctorant(e)s ainsi qu’au personnel permanent (la liste est longue et je suis s&ucirc r qu’ils vont se reconna&icirc tre facilement). Je réserve la fin de mes remerciements à ma famille pour leur soutien quotidien.

说明：  经典书籍 剑桥大学大学出版社： 无线通信基础(Book Description: The past decade has seen many advances in physical layer wireless communication theory and their implementation in wireless systems. This textbook takes a unified view of the fundamentals of wireless communication and explains the web of concepts underpinning these advances at a level accessible to an audience with a basic background in probability and digital communication. Topics covered include MIMO (multi-input, multi-output) communication, space-time coding, opportunistic communication, OFDM and CDMA. The concepts are illustrated using many examples from real wireless systems such as GSM, IS-95 (CDMA), IS-856 (1 x EV-DO), Flash OFDM and UWB (ultra-wideband). Particular emphasis is placed on the interplay between concepts and their implementation in real systems. An abundant supply of exercises and figures reinforce the material in the text. This book is intended for use on graduate courses in electrical and computer engineering and will also be of great interes)
