Apparatus and Method for avoiding mutual distorsion for a multi-transmitter mobile phone

摘要

There is provided a communication apparatus (21), comprising a plurality of radio transmitter sections (4a, 6a), which is capable of suppressing unnecessary radiowaves from being generated due to mutual modulation distortion without increasing the size and weight of the whole apparatus. When the communication apparatus (21) receives a UI (RT = paging, MM = -, CC = -) signal from a radio base station and it coincides with the ID of own station during when transmitting means (6a) of a PHS RF section (6) is operative, it rejects a process for the request of "Call Incoming in PDC" accompanying to that and makes no transmission by the PDC transmitting means (4a). Therefore, no transmission is made simultaneously by the PDC transmitting means (4a) and the PHS transmitting means (6a) and the quality of the radiowaves transmitted from the PHS transmitting means (6a) may be kept high. <IMAGE>
