Under exploiting MIMO-OFDM communication system spatial signal resources, diversity algorithms based on one preamble symbol for MIMO-OFDM frame and symbol timing synchronization are presented in this paper.
应用MIMO-OFDM无线通信系统的空间信号资源,提出了基于单个前导符号的MIMO-OFDM系统帧定时和符号定时同步的分集算法,以克服高速无线多径信道中深衰落对MIMO-OFDM系统定时同步性能的影响,给出了具体的帧定时、符号定时同步的分集算法以及在高速无线多径信道COST207模型下帧定时和符号定时同步的仿真结果。
A low-overhead oriented method for fast frequency offset estimation of OFDM is proposed,which uses only one OFDM symbol with L identical parts as preamble.
提出一种基于前导符号为L等分结构的OFDM快速频偏估计的新方法,该方法只需一个OFDM符号作为前导符号,数据开销较小。
16d OFDM symbols\' structure was outlined,and in accordance with the characteristics of OFDM channel estimation,a new channel estimation algorithm based on the pilot and preamble was proposed.
16dOFDM系统的符号结构进行了概述,结合OFDM信道估计的特点,提出了一种基于前导符号和非均匀导频的信道估计的算法,并在SUI1-SUI6信道环境下,用MATLAB对其性能进行了仿真。
Add leading char:~~Prefixes each line with the specified character.
添加前导字符:~~在原始邮件的每一行前添加指定的前导字符。
Enter an extension(without any leading characters):
输入扩展名(不可带有任何前导字符):
If the leader should fill all space on a line, the max length of the leader should be at least as large as the width of the column.
如果前导字符需要在一行中填充空格，那么前导字符的最大长度至少与列的宽度相同。
If the leader's length is too long to fit in the area, the leader will begin a new line.
如果前导字符长度太长，与整个区域明显不适应，那么它将会令起一行。
A previous version Private Character font file will be imported
将导入前几版本的专用字符字体文件
Returns a copy of a string without leading spaces
返回一个没有前导空格的字符串的副本
Any leading or trailing white space characters will be removed from each field, element or attribute.
任何前导或后继的空格字符将会从每个字段、元素和属性中删除。
Kanji characters cannot be inputted with the current font.
