METHOD FOR PROCESSING SIGNAL OF WIRELESS COMMUNICATION SYSTEM BY USING DIGITAL SIGNAL PROCESSOR AND APPARATUS FOR THE SAME

摘要

PURPOSE: A method for processing the signal of wireless communication system by using a digital signal processor(DSP) and an apparatus for the same are provided to improve the quality of the communication by extracting an original signal for each channel and removing a needless signal by using the DSP after the radio frequency(RF) signal of the transmitter/receiver of the wireless communication system is converted into a digital as well as to transmit a high quality signal at a long distance transmission through various transmission medium. CONSTITUTION: A method for processing the signal of wireless communication system by using a digital signal processor(DSP)(200) includes the steps of: converting the radio frequency(RF) signal into an intermediate frequency(IF), converting the IF of analog signal into a digital signal, down-converting the digital signal into a baseband digital signal and DSP processing by exactly filtering the frequency of the corresponding channel through passing a finite impulse response(FIR) filter, converting the DSP processed digital signal into an analog signal of intermediate frequency and converting the IF into the RF signal.
