Full duplex (FD) systems are able to transmit and receive signals over the same frequency band simultaneously with potential of even doubling spectral efficiency in comparison traditional half (HD) systems. When combined relaying, FD expected dramatically increase throughput future wireless networks. However, degrading effect self-interference (SI) due simultaneous transmission reception at rel...

In a cognitive radio context under spectrum sharing constraints, a secondary network may transmit concurrently with the primary one as long as the communication of this latter is not compromised. For such an operation, a maximum allowable interference level at the primary receiver is defined, and secondary users (SUs) should take into account this threshold during the transmission in order to a...

Abstract With the massive growth of wireless networks comes a bigger impact collisions and interference, which has negative effect on throughput energy efficiency. To deal with this problem, we propose an in-band collision interference detection scheme based full-duplex technology. study its performance, compare efficiency performance traditional half-duplex symmetric transmissions. Our analysi...
