OFDM
OFDM很容易在具有时延扩展或等效频率选择性的信道上使用。
频率选择性信道的特征在于延迟扩展或相干带宽，其测量频率中的信道去相关。
相干带宽与均方根（RMS）时延扩展成反比。
通过选择与信道相干带宽相关的子载波间隔，OFDM可以用于将频率选择性信道转换成频率平坦子信道的并行集合。
适合于平坦衰落信道的技术可以直接应用。(OFDM is simple to use on channels that exhibit time delay spread or, equivalently, frequency selectivity.
Frequency selective channels are characterized by either delay spread or coherence bandwidth which measures the channel decorrelation in frequency.
The coherence bandwidth is inversely proportional to the root-mean-square (rms) delay spread.
By choosing the sub-carrier spacing properly in relation to the channel coherence bandwidth, OFDM can be used to convert a frequency selective channel into a parallel collection of frequency flat subchannels.
Techniques that are appropriate for flat fading channels can then be applied in a straight forward fashion.)

huffman
霍夫曼编码的具体方法：先按出现的概率大小排队，把两个最小的概率相加，作为新的概率 和剩余的概率重新排队，再把最小的两个概率相加，再重新排队，直到最后变成1。每次相 加时都将“0”和“1”赋与相加的两个概率，读出时由该符号开始一直走到最后的“1”， 将路线上所遇到的“0”和“1”按最低位到最高位的顺序排好，就是该符号的霍夫曼编码。(Specific methods Huffman coding: the probability of emergence of the size press line, the two smallest sum probability, as a new probability and the probability of re-queue the remaining, then the minimum of two probabilities are added, and then re-queue, until finally become one. Each time the sum will be 0 and 1 Fu added two probabilities, when read by the symbol has come to begin the final 1 , the route will encounter a 0 and 1 at the lowest to the highest bit of the right order, that is the symbol of the Huffman coding.)
