说明：  排队问题仿真的目的是要寻找服务对象与服务设置之间的最佳配置，保证系统具有最佳的服务效率与最合理的配置，通过matlab平台对单服务台有限队长的排队系统进行 过程仿真 可以协助设计人员分析顾客的需求 从而合理规划出符合实际条件的服务设施(The purpose of the queuing simulation is to find clients and the best allocation between service settings, ensure that the system has the best efficiency and the most reasonable configuration, the single desk by the limited matlab platform captain Simulation of queuing systems can be help designers analyze the needs of customers in order to meet the actual conditions of rational planning of services and facilities)

一个OFDM符号128个有效符号，插入128个虚拟子载波 符号率（即有效数据率）fsymbol，而发送速率（需要包括虚拟子载波）2fsymbol 输入的数据需要2倍的发送数据率，以便进行内插，实现位定时跟踪，即4倍fsymbol采样率的调制信号 OFDM symbol Nfft=128 points 一个OFDM符号数据点 Nfft*2 = 256 ， Guard Interval点 ＝Ng*2=64 ( a OFDM symbol 128 effective symbols, insert 128 virtual sub-carrier symbol rate (i.e. valid data rate), and fsymbol sending rate (need to include virtual sub-carrier) 2fsymbol input data need 2 times the sending data rate for interpolation, realize a timing tracking, namely fsymbol sampling rates four times the modulation signal OFDM symbol Nfft = 128 points a OFDM symbol of data points Nfft* 2 = 256, Guard Interval point = Ng* 2 = 64 )
