PROBLEM TO BE SOLVED: To provide a method for giving the performance of STS, OTD, PSTD by using asymmetric sweep PSTD(phase sweep transmit diversity) transmission. SOLUTION: This method includes a step for separating signals s1 including a first STS/OTD signal into a signal s1 (a) and s1 (b), a step for separating a signal s2 including a second STS/OTD signal into signals s2 (a) and s2 (b), a step for phase-sweeping the signal s1 (b) by using a first phase sweep frequency signal, a step for phase-sweeping the signal s2 (b) by using a second phase sweep frequency signal, a step for adding a phase sweep signal s2 (b) to the signal s1 (a), and a step for adding the phase sweep signal s1 (b) to the signal s2 (a). The first and second phase sweep frequency signals are constituted so as to remove self guiding interference caused by phase-sweeping the signals s1 (b) and s2 (b).
