摘要
The digital signal modulation system has four states with four symbols. Each number set has two binary numbers corresponding to a complex plane quadrant. Supplementary binary figures are added to correct reception errors. The coding correction method has products or turbo correctors providing phase rotation transparency. The two I and Q bits are placed on different lines but the same column. Coding correction is carried out line by line and over adjacent columns. The coding bits and sent bits are placed in the same way,
