摘要

Topic The time offset of the finger of the receiver has been based on the time offset of the peak where the transmission signal of base station is received in antenna diver city environment. In the system of the multiple pass spread which you cannot ignore, as for the time offset of the peak where the transmission signal of base station is received as for the necessity to be same in the position it is not. With 1 execution examples, as for the demodulator for the signal from each base station antenna the same offset for recovering is used, the error signal is decided on the basis of the pilot signal sampling which it precedes and follows to the time offset and. The error signal is averaged, is used in order to pursue the Iriki signal by the time pursuit loop. With another execution example, as for the demodulator of the signal from each base station antenna the signal is pursued with the time offset which differs vis-a-vis each finger. Desirable execution example depends on the method of being used in order to multiplex the data in the many transmission antenna depending upon base station. Selective figure Figure 4
