Patent attributes
In a slot format of a received signal, AGC gain update timings (t1 to t4) are shifted every time to disperse and reduce an influence of a noise attributable to a direct current component specific to direct conversion which is accompanied by AGC gain update. In particular, in the case where each of slots in the received signal includes an information portion (data) having a larger code correcting capability and an information portion having a smaller code correcting capability (TPC (transmission power control), TFCI (transport format combination indicator), PILOT), the AGC gain update timing is generated while being shifted in the former information portion, thereby reduce the influence of the noise. When the amount of shift of the AGC gain update timing is set to be larger than that of one symbol of the received signal, the influence of the noise accompanied by the AGC gain update is further reduced.
