The present invention relates to a communication device and a method of processing input data, comprising: a detection unit receiving the input data to perform the packet detection process; an automatic gain controller generating an adjusted data and an gain control parameter once packet is detected; a signal processor detecting at least one of desired signal, noise and interference; a demodulator demodulating the processed data for generating demodulating data; a pre-detection module determining whether a potential error has occurred in the demodulated input data by a pre-detection method prior of completing retrieval of the data packet, and performing a selection to decide whether the components need to be terminated and which of the components need to be terminated if there is the potential error occurred on the demodulating data; and a baseband module performing a packet-based error check on the data packet upon completing retrieval of the data packet if there is no potential error occurred on the demodul
