Radio transmitting apparatus and gain control method for the same |
摘要 |
Gain control is performed on an input signal to an orthogonal modulator used in a radio transmitting apparatus in such a manner that the level of the input signal falls within the proper operation range of the orthogonal modulator. At the time of amplifying and outputting the output of the orthogonal modulator, gain control is executed with the reciprocal of a control gain for the input signal to the orthogonal modulator. Accordingly, the input to the orthogonal modulator of an adaptive array antenna can be compensated within the proper range to ensure the proper operation of the orthogonal modulator. <IMAGE> |
