In the scenario of dynamic spectrum access application for orthogonal frequency division multiplexing (OFDM)-based cognitive radio systems, the out-of-band ...
Exploiting the fact that different sequences have different sidelobe power levels, the proposed algorithm employs a constellation expansion-based iterative ...
Bibliographic details on Constellation expansion-based sidelobe suppression for cognitive radio systems.
Figure 4.15 shows a similar trend in the suppression of sidelobe levels by apply- ing constellation expansion for a QPSK-OFDM modulated system. The normal ...
Regular paper. Constellation expanded active interference cancellation technique for suppression of out-of-band radiation in OFDM based cognitive radios.
Constellation expansion (CE) is one of the methods for reduction of OFDM sidelobes that has a good performance. In CE, no side information needs to be ...
