According to all bit datas are divided into multiple bit data groups, each ratio further according to the difference of data type or application scenarios
Bit data in special data group belongs to identical data type or application scenarios.
Then again by the symbol-modulated to every group of bit data, such as QAM, OQAM, PBSK etc., by each bit data
Group is modulated into a set of symbols.Such as 3 bit data groups have just been modulated into 3 set of symbols respectively, and in each set of symbols
All symbols to be passed sign pattern all having the same for including, that is, the data type of corresponding bit data group.Tool
