很实用的群优化智能算法，计算粒子群算法的源代码，所需优化的目标函数命名为fitness即可。(a partical swarm algorithm)

说明：  移动通信系统 信道，接收机等的MATLAB源代码，较详细(mobile communications MATLAB demo)

说明：  完成从信源到目的端信息的传输与接收，信源信息经过QPSK调制，然后经过瑞利信道，在目的端仿真其译比特率（BER）。(BER simulation.)

projet 1 is very importand

Plots the radiation intensity pattern of a rectangular antenna array of identical dipole elements using the product of element pattern and array factor to get the Radiation Pattern

Economic dispatch is the short-term determination of the optimal output of a number of electricity generation facilities, to meet the system load, at the lowest possible cost, subject to transmission and operational constraints. The Economic Dispatch Problem is solved by specialised computer software which should honour the operational and system constraints of the available resources and corresponding transmission capabilities. In the US Energy Policy Act of 2005 the term is defined as the operation of generation facilities to produce energy at the lowest cost to reliably serve consumers, recognising any operational limits of generation and transmission facilities.

画出地球，模拟不同时刻卫星位置，模拟用户位置，与可见卫星(Draw the earth, the simulation satellite location, different time simulated user s location, with the visible satellites)

双向DC，plecs仿真，带闭环控制，可以联合仿真(Bidirectional DCplecs simulation)

说明：  较为详细和全面的介绍了MATLAB在仿真系统中应用。(More detailed and comprehensive introduction to the MATLAB application in the simulation system.)

Just have a look at it for OFDM....nice code
