下采样
1.
After down-sampling the training symbol into several L-point sub-symbols and demodulating part of them by means of a new FFT algorithm considering the factor of the fractional frequency offset,the scheme estimates the integer frequency offset by finding the maximum magnitude of the combined resulting frequency domain signals.
该方法将1个等分的OFDM训练符号下采样为大量长度为点的OFDM子符号,然后结合小数频偏估计值,设计新的快速傅里叶变换(FFT)算法解调一部分OFDM下采样符号,再合并结果,寻找频域峰值,从而对整数频偏做出估计。
2.
In order to solve the problem that the traditional down-sampling methods can not adapt to the different application requirements,an inherent identity of implementation technique between down-sampling and interpolation of image scale transform is proposed,and then many advanced interpolation methods can be used in down-sampling.

【诗文】：
蒿火目。藜羹腹。书生宁有封侯骨。长须奴。下泽车。艰关险阻，谁教涉畏途。半生落漠长安道。一事无成双鬓老。南辕胡。北辕吴。功名富贵，情知不可图。槐安梦。鼓笛弄。驰骤百年尘一哄。陶渊明。张季鹰。一杯浊酒，焉知身後名。有溪可渔林可缴。须信在家贫也乐。熊门春。＊江云。几时作个，山间林下人。
