Abstract
A transmission power detecting apparatus of a CDMA system is disclosed by which since the power detection of the RF CDMA signal is digitally performed and no RF device (an RSSI detector) which is sensitive to a temperature change is used, a power of the RF CDMA signal can be more accurately detected. In addition, since an IF analog CDMA signal to be measure is sampled and then an average power of the sampled digital IF CDMA signal is obtained, accuracy in power detection and transmission power adjustment can be accomplished. Moreover, since the power of the baseband digital CDMA signal containing a traffic is detected to provide a reference value for adjusting the power of the RF CDMA signal, an error generated in determining a power of the RF CDMA signal as in the conventional art can be reduced.
