Abstract :
The paper proposes a cascaded Radio on Fiber and digital millimeter-wave Radio on Radio entrance link for small cell mobile access. By utilizing wideband property of millimeter-wave, RF signals such as cellular, WiFi, or WiMAX can be digitalized and transferred to remote base station over digital RoR link. This paper will show the system configuration, and theoretical evaluations of the link design, and a basic experiment shows some results of EVM measurements for WiMAX signals. The influence of the sampling rate and quantization level at ADC will be discussed.
