Abstract

Telecommunication technology is now growing rapidly because of the need for communication that is used by the community as a service to support the needs of life in terms of the use of information exchange is increasing. This information exchange uses a medium or path called transmission media. In transmission there is a process called modulation. Modulation is the process of converting a carrier signal that has a high frequency so that the signal is capable of carrying information. Changes in the carrier signal are adjusted by the signal information parameters sent. One of the values that determines the modulation system quality is the Bit Error Rate (BER) by looking at the effects of the Eb/N0 and SNR values. In this report the modulation used is Quadrature Phase Shift Keying (QPSK). QPSK has four modulated signal forms, QPSK is able to modulate information signals of high frequency signals with quite good bitrate so that it can be used in 5G technology. 5G technology is a fifth generation technology that covers a frequency range of 30 GHz to 300 GHz, and allows data rates of 20 Mbps to a distance of 2 Km. The Testing in this simulation uses input data as much as 1000 random symbol data and Eb / N0 level with a range of 2 dB. The results of BER simulation performance with BER QPSK AWGN at Eb / N0 level value of 4 dB is obtained amounting to 0.18642 with Eb / N0 in the theory valued at 0.18611, while the performance results of BER simulation with BER Rayleigh Fading QPSK at Eb / N0 level of 34 dB are obtained amounting to 9,895.10-5 with Eb / N0 in theory valued at 9.95.10-5. Keywords: transmission, modulation 5G, QPSK, BER, SNR, AWGN, Rayleigh Fading.
