Abstract

The ever growing broadband internet applications have increased the traffic capacity and demand for wide\nnetwork coverage. Radio over fiber (ROF) is a combination of Wireless as front end and Optical Fiber Communication as\nBack-haul networks. ROF network provides mobility for users with high quality bandwidth and better geographical access. In\nthis paper, we analyze Q-factor, BER and eye patterns for various Modulation schemes such as MSK, DPSK, OQPSK, CPFSK\nand Q-CPFSK (Quadrature) by means of Bit-rate and fiber length. Our Simulation results shows that Q-CPFSK gives better\nperformance compared to other schemes at Optical Carrier Frequency of 193.1THz.
