对声音信号进行各种处理实现了声音的均衡等功能(The audio signal processing to achieve various functions of the sound equalization)

Identifying overlapping period in time series. Required input: X = structure with in every cell (X{cell}) a measurement station. every cell has its first three columns as [year,month,day] Output: begin_date = is beginning date of overlapping periods end_date = end date of overlapping periods output = structure with overlapping periods filtered numcell = number of measurement stations

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)
