Abstract
A receiver, an automatic gain controller suitable for the receiver, a control signal generator suitable for the automatic gain controller, a reception power controller using the automatic gain controller and a communication method using the receiver. The instantaneous power of a received signal output from a variable gain amplifier or attenuator is detected by a power detector. The detected instantaneous power is quantized by a comparator and filtered through a random walk filter. An up-down counter counts up or down in accordance with the increment signal or the decrement signal obtained by filtering. In this manner, error in the gain control of the variable gain amplifier or attenuator is obtained.
