A code generation section 106 outputs a primary code stored in a code storage section 105 at a predetermined timing. A despreading section 107 measures a delay profile by correlation between the output signals of an analog-to-digital conversion section 104 and the primary codes of the above code generation section 106. A user judgment section 111 detects a maximum path for each user, based on the above delay profiles. An electric-field-strength calculation section 112 calculates the sum of amplitude values Rcell of the own cell from an electric power Pi of the maximum path PAi for each user i. A gain-coefficient calculation section 113 calculates a gain coefficient so that the above Rcell becomes equal to a target value. Thereby, AGC may be performed with good accuracy, and deterioration in the received quality may be prevented, when an MUD type interference canceller is used. <IMAGE> |
