Abstract

The development of telecommunications system in modern technology is increasing widely so that the process can take place more quickly and efficiently, one of which was the use of Software Defined Radio (SDR). SDR is a radio communication system where the components that have been typically implemented in hardware (mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on computer or embedded system supported by GNU Radio Companion and USRP. This research is designing the video transmission using based on Software Defined Radio using GNU Radio and USRP. Some hardware function is replaced by the software in GRC block in GNU Radio. USRP B200 is used to translate the signal to the exact radio frequency. In testing the video transmission, the parameters of the FFT length of OFDM, 128, 256, and 512 and with different type of modulation was tested. The video transmission with the best result was performed using 512 FFT lengths.
