Abstract:
A receiving apparatus converges a gain to a target gain even when a fish bone effect signal is included having a low power period in which signal power decreases abruptly compared to average signal power. The receiving apparatus (100) receives a signal including the fish bone effect signal having the low power period (FBE signal period) in which signal power decreases abruptly compared to average signal power. A FBE detecting section (133) detects an FBE signal period of a low power period based on a gain error corresponding to a difference between target power and average signal power of the received signal of the adjusted gain. Further, the gain error correcting section (134) selects a lower value than 1 as a convergence coefficient in the FBE signal period of a low power period, multiplies the gain error with the selected convergence coefficient and corrects the gain error.
