Method and apparatus for automatic gain control of a multi-carrier signal in a communication receiver

A receiver connected with the corresponding number's inner ring has and outer ring a FILTERING processing a FILTERING multi-carrier signal. By correcting schema proccessing by for indicating with a limited quantity in multi-carrier signal first bit number. The first bit number provides and loop FILTERING for quantization of multi-carrier signal, achieve highest quantization layer. The received signal and estimating achieves the predetermined ON a threshold, outer ring a FILTERING higher than the second bit number of the first bit number permits to act according to the first bit number and second bit number difference interference and method for quantization possibly to a. When the received signal and estimating wherein the predetermined OFF of the threshold; the outer ring a FILTERING and uses the first bit number.
