An apparatus includes an amplitude converter, receiving a complex baseband signal to output an amplitude thereof, a memory, receiving an amplitude from the amplitude converter as an address to output an inverse gain associated with the amplitude, a reciprocal converter receiving an output of the memory as input and outputting a reciprocal of the memory output, a FIR filter for filtering an output signal of the reciprocal converter, a reciprocal converter receiving an output of the FIR filter as input to output a reciprocal of the output of the FIR filter, and a complex multiplier for executing complex multiplication of the complex baseband signal and an output of the reciprocal converter.
