OFDM,实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。在向B3G/4G演进的过程中，OFDM是关键的技术之一，可以结合分集，时空编码，干扰和信道间干扰抑制以及智能天线技术，最大限度的提高了系统性能。(OFDM)

本文主要通过对蜂窝无线通信系统信道、扇区化等的建模，使用MATLAB仿真实现对系统的中断概率的计算，并中断概率的大小分别作为衡量系统性能的标准。(This paper mainly modeled on the cellular wireless communication systems of channel, division of sectors and so on , by using the method of MATLAB, and realized to the calculation of blocking probability , and regarded the size of outage probability as a measure of system performance.)

详细介绍了MATLAB语言精要及动态仿真工具SIMULINK，希望大家喜欢。(detail the essence of MATLAB simulation and dynamic simulation tool, hope you like them.)

TSP can be defined as a problem where starting from a node it is required to visit every other node only once in a way that the total distance covered is minimized. After an initial solution a neighborhood solution is selected by an exchange of a randomly selected pair of nodes. The randomly generated neighbor solution is selected if it improves the solution else it is selected with a probability that depends on the extent to which it deteriorates from the current solution.
