It is also shown that in cases where the secondary network is unable to achieve higher rates by increasing the total power and/or interference threshold, utilizing TCM-OFDMA acts as a smart alternative. 展开 关键词: interference alignment cognitive radio MIMO interference channel multi-users ...

Furthermore, the long interspersed nuclear element-1 (LINE-1) L1MC1 transposon inserted in DPYD intronic transcript 1 (DPYD-IT1) lncRNA with its parasites, TcMAR-Tigger5b and pair of Alu repeats appears to be the “weakest link” within the DPYD gene liable to break. Identification of the...
If there is no idle channel, SUs will wait for the response of the central base station (CBS). Based on this queuing feature, a great deal of research has been proposed to analyze the cognitive radio system using queuing theory and Markov chains. In [16], a queuing access scheme based ...
While the consideration of routing may be one of the appeals of this work, it is not an essential issue for a CRSN. Thus, this work may be suitable for very large-scale CRSNs. A similar drawback can be inferred from grid-based channel assignment [30]. The Markov decision process is ...
