Abstract :
We describe a radio-over-fiber (ROF) based ultra-wideband (UWB) transmission system. In a multi-cell environment using ROF technology, the performance of UWB signal transmission with different modulation schemes is evaluated in a realistic channel model based on a modified Δ-K model. Then, we investigate the effects of multipath interference and delay time at the overlapped area on the performance of UWB in terms of link margin and bit error rates. The performance of a RAKE receiver with maximal-ratio combining is also studied using the optical and wireless link analysis simulator, Photonics CAD.
