Eliminating co-location radio interference with photonic-enhanced spectrum management in cognitive radio networks

An Optical Technique for Radio Frequency Interference Mitigation

“…There have been numerous demonstrations of photonic techniques for interference suppression for the applications noted above [9]. The majority of the work in photonics-based radio-frequency (RF) interference mitigation can be broadly placed into two categories: cancellers [10]- [13] and frequencydomain filters [14], [15]. The latter can utilize a variety of architectures but is presented with the difficulty of manipulating optical signals near 200 THz with RF resolution.…”
