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