说明: 某厂生产甲乙两种口味的饮料,每百箱甲饮料需用原料6千克,工人10名,可获利10万元 每百箱乙饮料需用原料5千克,工人20名,可获利9万元.今工厂共有原料60千克,工人150名,又由于其他条件所限甲饮料产量不超过8百箱.问如何安排生产计划,即两种饮料各生产多少使获利最大.进一步讨论:
1)若投资0.8万元可增加原料1千克,问应否作这项投资.
2)若每百箱甲饮料获利可增加1万元,问应否改变生产计划.
(Factory production of beverages and B in two flavors, each box 100 need a drink six kilograms of raw materials, workers 10 to 100,000 yuan profit B beverage cartons per cent five kilograms of raw materials needed, workers 20, the profitability of 90,000 yuan. this plant a total of 60 kilograms of raw materials, 150 workers, and because other conditions do not yield a beverage cartons more than 8 per cent. ask what arrangements the production of projects, namely the production of two the number of drinks to make the biggest profit. further discussion : 1) if the investment 08,000 yuan to increase one kilograms of raw materials and asked whether we should make this investment. 2) If a beverage cartons per cent profit increase 10,000 yuan and asked whether or not to change the production plan.)

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
(128 of an OFDM symbol of a valid symbol 128 inserted virtual sub-carrier
Symbol rate (the effective data rate) fsymbol sending rate (including virtual subcarriers) 2fsymbol
Of the input data needs to be 2 times the transmission data rate, in order to carry out the interpolation, to achieve the bit timing tracking, i.e. four times the sampling rate modulation signal fsymbol
OFDM symbol Nfft = 128 points
One OFDM symbol data points nfft* 2 = 256, the Guard Interval dot = Ng* 2 = 64)
