摘要 |
The invention provides a mobile communication terminal for a CDMA system which uses both a continuous pilot signal and an intermittent pilot signal for phase error detection and correction to assure synchronous detection. The apparatus includes a first pilot signal despreading section (22-1...22-3) for despreading a first continuous pilot signal spread with a spread code different from a spread code of a communication channel, a second pilot signal despreading section (26-1...26-3) for despreading a second intermittent pilot signal inserted in a data signal and spread with a spread code same as the spread code for the data signal, first and second pilot demodulation sections (23a,23b), and first and second respective phase error estimators (23c,23d) producing phase error amounts that are wheighed (23b) according to the relative signal strengths (23e,23f) with which the first and second pilots have been received (23g,23i). <IMAGE> |
