针对MIMO-OFDM系统中期望最大化(EM)信道估计算法在高信噪比(SNR)下带来的误差地板(EF)现象,且OFDM符号的数据传输效率随发射天线数的增加而明显降低,提出一种改进的高效EM信道估计算法。该算法首先引入一种准确的等效信号模型并推导出一种修正的EM算法,改善了EM算法在高SNR下的性能 在多个OFDM间利用相位正交导频序列来提高数据传输效率,同时进行联合信道估计以提高估计性能。仿真实验验证了所提算法具有更高的信道估计性能和更高的数据传输效率。(For multiple-input multiple-output with orthogonal frequency division multiplexing(MIMO-OFDM) systems,the error floor(EF) phenomenon at high signal noise rate(SNR) was induced by the expectation maximum(EM) channel estimation algorithm.In addition,the data transmission efficiency was declined obviously with the increasing number of transmit antennas.According to these problems,an improved and efficient EM channel estimation algorithm was pro-posed.Firstly,an accurate and equivalent signal model was introduc...)

code
在给定字符串中找出单词（ “单词”由小写字母字符大写字母和构成，其他非字母字符视为单词的间隔，
如、问空格号、数字等等；另外单个字母不算单词）；找到单词后，按照长度进行降序排序，
（排序时如果长度相同，则按出现的顺序进行排列），然后输出到一个新的字符串中；如果某个单词重复出现多次，
则只输出一次；如果整个输入的字符串中没有找到单词，请输出空串。输出的单词之间使用一个“空格”隔开，
最后一个单词后不加空格。(Identify the word (" word" character from the uppercase and lowercase letters constituted, other non-alphabetic characters as word spacing, such as asking a space number, number, etc. another is not a single letter word) in a given string find words after descending order according to length, (if the same length, the order stated that appears when sorting arranged), and then output to a new string If a word is repeated several times, only output once If the entire input string is not found in word, outputs an empty string. Used between the output of a word " space" separated, no spaces after the last word.)
