Abstract
A receiver detects a highly precise approximate value of the power of a reception signal with a high speed. A first comparator outputs a larger of a component I and component Q of a reception signal as a first output value and a smaller as a second output value. A 3-bit shift register multiplies the first output value by ⅛, a subtractor subtracts the by-⅛-multiplied value from the first output value, and a 1-bit shift register multiplies the second output value by ½. A 2-bit shift register multiplies the by-½-multiplied value by ¼, a first adder adds the first output value and the by-¼-multiplied value, and a second adder adds an output value from the subtractor and an output value from the 1-bit shift register. A second comparator outputs the value of a larger result of the two additions as an approximate power of the reception signal.
