Abstract
A radio communication device which when transmitting both a first information sequence, on which π/4-shift differential phase shift modulation is performed, as a delayed wave and a second information sequence, on which a differential phase shift modulation is performed, as an advance wave by using a PADM (Per transmit Antenna Differential Mapping) method, interchanges signal points respectively belonging to quadrants which are one of a first quadrant and a third quadrant, a second quadrant and a fourth quadrant, the first quadrant and the second quadrant, the first quadrant and the fourth quadrant, the second quadrant and the third quadrant, and the third quadrant and the fourth quadrant, the signal points being included in signal points mapped onto a complex plane which consists of a real number axis and an imaginary number axis, to change the arrangement of the information sequence.
