Full-Duplex Enabled Cloud Radio Access Network
Full-duplex (FD) has emerged as a disruptive solution for improving the achievable spectral efficiency (SE), thanks to the recent major breakthroughs in self-interference (SI) mitigation. The FD versus half-duplex (HD) SE gain, in the context of cellular networks, is however largely limited by the mutual interference (MI) between the downlink (DL) and uplink (UL). A potential remedy for tacklin...
متن کاملCognitive Radio Networks with Full-duplex Capabilities
Inspired by recent developments in full-duplex (FD) communications, we consider an opportunistic spectrum access (OSA) network in which secondary users (SUs) are capable of partial/complete self-interference suppression (SIS). This enables them to operate in either simultaneous transmit-and-sense (TS) or simultaneous transmit-and-receive (TR) modes, with the goal of achieving improved primary u...
متن کاملPower Control for Underlay Cognitive Radio Networks with Full - duplex
Radio communication, one of core contents in wireless communication, is facing a great crisis of running out of resource. Unlike other energy crisis which can be solved by using all kinds of alternative energy, the only resource of radio communication is channel, in another word, spectrum. Rather than sticking on trying to achieve the rest one percent of capacity, more and more scholars start t...
متن کاملFull-Duplex Cooperative Sensing for Spectrum-Heterogeneous Cognitive Radio Networks
In cognitive radio networks (CRNs), spectrum sensing is critical for guaranteeing that the opportunistic spectrum access by secondary users (SUs) will not interrupt legitimate primary users (PUs). The application of full-duplex radio to spectrum sensing enables SU to carry out sensing and transmission simultaneously, improving both spectrum awareness and CRN throughput. However, the issue of sp...
متن کاملFull Duplex Wireless Communications for Cognitive Radio Networks
As a key in cognitive radio networks (CRNs), dynamic spectrum access needs to be carefully designed to minimize the interference and delay to the primary (licensed) users. One of the main challenges in dynamic spectrum access is to determine when the secondary (unlicensed) users can use the spectrum. In particular, when the secondary user is using the spectrum, if the primary user becomes activ...
