摘要 <p><P>PROBLEM TO BE SOLVED: To prevent the output level of a transmission wave from being fluctuated even if antennas are switched by antenna diversity control in a receiving mode in communication equipment that can perform transmission and reception at the same time. <P>SOLUTION: A transmitting part 131 is provided with a transmission wave adjusting part 131a, and a digital processing part 14 is provided with a control signal adjusting part 14a. Even though a transmission wave C deteriorates because passing loss occurs in a transmission band pass filter 121 when receiving antennas are switched on the basis of the antenna diversity control, the control signal adjusting part 14a deforms the waveform of a transmission output control signal B and the transmission wave adjusting part 131a adds the deteriorated portion to the transmission wave C in advance on the basis of the deformed transmission output control signal B so as to fill up the deteriorated portion of the transmission wave C that is formed at the time of switching the antennas on the basis of the deformed transmission output control signal B. <P>COPYRIGHT: (C)2004,JPO</p>
