Summary:
The demand for broadband data transmission has rapidly increased due to the need of enormous data usage. New applications require high bandwidth for transmitting the data such as voice and video over 3G/4G mobile communication, wireless local area network and Gigabit Ethernet. To cope with this situation, broadband data transmission over Radio over Fiber (RoF) has been chosen. Here, a RoF link is created using a 1550nm laser diode (LD) and a photodiode (PD). By carefully selecting the LD and PD, broadband data transmission of ~1.5 GHz can be possibly achieved, measured by the Vector Network Analyzer (VNA). Finally, the modulated data of BPSK, and QAM modulation at 900MHz carrier frequency from the output port of first Universal Software Radio Peripheral (USRP) have been generated and transmitted over the RoF link to the input port of second USRP to measure the link performance such as Bit-Error-Rate (BER), including the noise figure calcualtion of the link.
