PROBLEM TO BE SOLVED: To solve the problem that a known signal modulation system can not generate signals with satisfactory pure phases. SOLUTION: A system operable to modulate a signal according to phase-shift keying (PSK) modulation includes a translator and a phase modulation system. The translator receives data signals and translates the data signals into control signals, where the number of control signals is greater than the number of data signals. The phase modulation system includes phase modulators. Each phase modulator receives a control signal and modulates a communication signal according to the control signal.
