Abstract
A communication device and a method of processing input data. The communication device, processing input data constituting at least one of data packet comprises a detection unit, an Automatic Gain Controller (AGC), a signal processor, a demodulator, a pre-detection module, and a Baseband module. The detection unit receives the input data to perform the packet detection. The Automatic Gain Controller, coupled to the detection unit, generates an adjusted data and a gain control parameter once packet is detected. The signal processor, coupled to the AGC, performs the data signal processing includes at least one of analog to digital transformation processing, radio frequency processing and baseband processing, and detects at least one of the desired signal, noise and interference. The demodulator, coupled to the signal processor, demodulates the processed data into a processed data according to at least one processing function of noise reduction, interference reduction, and signal compensation. The pre-detection module, coupled to the demodulator, determines whether a potential error has occurred in the demodulated input data by a pre-detection method prior completing retrieval of the data packet for performing a packet-based error check sequence, and performs a selection to decide whether the components need to be terminated and which of the components need to be terminated if there is a potential error occurred on the demodulated input data. The Baseband module, coupled to the demodulator, performs 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 demodulated input data.
