PURPOSE: A transceiving digital signal processing device for compensating gain flattening in band is provided to relax a standard about a flattening in band in realizing RF/IF circuit by improving gain flattening in band through an FIR filter in a transceiving unit of an existing system. CONSTITUTION: A transmission FIR(Finite Impulse Response) filter(411) performs shaping of the initial set data for converting an initial setting data into a signal having a predetermined pass band. A comparator(413) compares the converted initial setting data for generating a control signal and deterioration information which is feedback from a receiver. |
