DAIMA
OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀(CP)可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是,过长CP会使得数据传输效率降低。可以采用最小均方误差(MMSE)信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

利用熵值法判断某个指标的离散程度的。在信息论中,熵是对不确定性的一种度量。信息量越大,不确定性就越小,熵也就越小;信息量越小,不确定性越大,熵也越大。根据熵的特性,我们可以通过计算熵值来判断一个事件的随机性及无序程度,也可以用熵值来判断某个指标的离散程度,指标的离散程度越大,该指标对综合评价的影响越大。
因此,可根据各项指标的变异程度,利用信息熵这个工具,计算出各个指标的权重,为多指标综合评价提供依据。(Using entropy method to judge the degree of dispersion of a certain index.)
