Abstract
Despreading means despreads a pilot signal included in a first received signal . Strength determination means determines the strength of the despread pilot signal. Integration control means determines the integration interval used by integration means , from the strength of the received pilot signal. The differences in strength detected by strength difference detection means are added together by the integration means over the period of time decided by the integration control means . The integration interval used by the integration means is made changeable according to the receiving environment. Accordingly, when there is the superior receiving environment, there is reduced the load imposed on the integration means when the integration means performs the processing operations. Therefore, there can be realized a superior CDMA receiver phase tracking system which dissipates a fewer amount of electric power.
