2018 arXiv   pre-print
We introduce the concept of a Rotman-lens spectrum decomposer (RLSD) real-time spectrum-sniffer (RTSS) for cognitive radio.  ...  Compared to a previously existing RTSS, the RLSD-RTSS offers the advantages of being 1) based an a simpler and lower-cost purely passive structure, 2) easier to design and easily amenable to tunability  ...  CONCLUSION We have presented and demonstrated a Rotman-lens spectrum decomposer (RLSD) real-time spectrum-sniffer (RTSS) for cognitive radio.  ...
