Comparison Between Analog Radio-Over-Fiber and Sigma Delta Modulated Radio-Over-Fiber [PDF]
IEEE Photonics Technology Letters, 2017 With the continuously increasing demand of cost effective, broadband wireless access, radio-over-fiber (RoF) starts to gain more and more momentum. Various techniques already exist, using analog (ARoF) or digitized (DRoF) radio signals over fiber; each with their own advantages and disadvantages.
