Claim 0:
1. A signal processing device, comprising:
a first modulation element that modulates a signal to any one of M1 (M1 is an arbitrary integer) patterns in a first range;
(k−1) (k is an integer that is greater than or equal to 2) second modulation elements that respectively modulate the signal to any one of M2 through Mk (M2 through Mk are arbitrary integers that are mutually independent of each other and M1) respective patterns in a second range through a kth range, respectively; and
a control unit that controls the first range for the first modulation element and the respective second range through the kth range for the (k−1) second modulation elements,
wherein the control unit performs control to make the respective second range through the kth range for the (k−1) second modulation elements narrower than the first range for the first modulation element.
