Abstract :
We demonstrate the creation of multiple spectral nulls, in a 10 Gb/s On Off Keyed signal with the help of DC balanced encoders. 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 10G signal and the wireless signal is studied for various wireless power levels, and comparisons are made to scenarios where encoding is not used. Results show significant system performance enhancements due to the reduction of interference, which is achieved by encoding the baseband data signal.
