Abstract: PROBLEM TO BE SOLVED: To perform AGC and DC compensation in a receiver.SOLUTION: A receiver comprises: an energy estimator for generating an estimate of the level of a received signal; an RF device to apply gain to the received signal; an AGC for controlling the RF device gain on the basis of the energy estimate; a first DC compensation loop for finely adjusting DC compensation of the received signal in a fast or slow tracking mode (FTM or STM); and a second DC compensation loop for coarsely adjusting a DC component of the received signal. AGC operations have three modes, namely, in acquisition, in connection, and in sleep.
