Abstract

Asymmetric Digital Subscriber Line (ADSL) system is an access technology that enables communication of data, voice and video simultaneously on copper access media. Data communication can not be avoided from the noise, not least ADSL systems are experiencing an error in delivery caused by the noise that makes the value of the bit error rate (BER) increase. Therefore, we need a way to reduce the noise so as to minimize the value of BER. To reduce noise and obtain the required value BER modulation method Quadrature Phase Shift Keying (QPSK) in ADSL systems. Visualization system is needed to determine the performance of the ADSL system and knowing that caused the BER. From the results of visualization by providing 64 bits of data input, constellation display have spread the data but does not distort the shape of constellation. When constellation entrance to the Additive White Gaussian Noise (AWGN) channel with a deviation between 0 dB - 20 dB and intervals of 2 dB, resulting BER value 0.3906 when the Signal to Noise Ratio (SNR) is 0 dB until BER is zero when the SNR range between 9 dB - 20 dB.
