In-band insertion of RoF LTE Services in OOK based PON's using line coding techniques

We demonstrate the creation of multiple spectral nulls, in a 10 Gb/s On Off Keyed signal with the help of encoders with inherent DC-balanced and minimum-bandwidth properties. Within a hybrid wired/wireless PON architecture, these generated nulls are subsequently used to transmit a wireless signal with 20 MHz of bandwidth carrying Long Term Evolution (LTE) service. The level of interference experienced on both the wired 10 G signal and the wireless signal was studied for various wireless power levels and the encoding order. Results show significant system performance enhancements due to the reduction of interference, which had been achieved by encoding the baseband data signal. Finally numerical simulations are employed to elaborate on performance of the encoded system.
