OFDM system can be implemented on GNU Radio, one type of SDR (software-defined radio). SDR is a transmitter and receiver system that uses digital signal processing to code, decode, and modulate data. GNU Radio is used as a transmitter and receiver model for quality measurements for the working of the OFDM system under various conditions. This measurement will compare real-time data transmission performance results through AWGN channels and dynamic channel models, namely Rayleigh Distributed (NLOS) and Rician (LOS). The specification of the OFDM system used in this study is to use GNU Radio software with BPSK modulation (Binary Phase Shift Keying). The simulation model’s output in the GRC during real-time data transmission via AWGN and Rayleigh distributed (NLOS) and Rician Distributed (LOS) model channels with GNU Radio is the performance of OFDM signals with the noise of 25mV, 50mV, 100 mV, and 200mV. The results of the research simulation obtained SNR values on AWGN, NLOS, and LOS channels directly proportional to noise. The SNR value is down significantly to four times the initial value.
