Abstract: PURPOSE: To attain signal arrangement corresponding to plural modulation values by using gray codes of coordinates of I and Q axes in the arrangement of QPSK signals as mother codes, and generating gray codes by extending so as to obtain all patterns from low-order bits around the coordinate axes. CONSTITUTION: When the I axis coordinate is taken notice of the arrangement of QPSK signals, gray code coordinates are 0 and 1. A 0 is added to the figures to form figures 00,01 and figures 10, 00, 01, 11 are formed by forming gray codes with a figure 1 with the figures 00, 01 inbetween. They are used for 16QAM coordinates with a higher dimension and the figures are arranged on the I and Q axes. Signals at symbol position are arranged by combining alternately figures of the I and Q axes. Thus, 4 symbols in the center are arranged in which high-order 2-bits are 00 and low-order 2-bits express every pattern. The coordinate expression method is extended to the application of 64QAM and 256QAM without extension of a ROM.
