Sentence examples for cognitive links from inspiring English sources

Satellite earth stations communicate with the GEO satellite through cognitive links, i.e., the licensed channels.

Yellow dotted line stands for cognitive links; black solid line strands for primary link.

OCC-MAC tries to balance the interference level and the contention level among cognitive links to utilize spectrum opportunities in a unified optimization framework.

By using an appropriate precoding design, the cognitive node aligns its transmitted signal to the unused primary eigenmodes and ensures an orthogonality between the primary and the cognitive links.

In [9], a spectrum server is utilized to find the optimal schedule that maximizes the average sum rate subject to a minimum average rate constraint for cognitive links using a graph-theoretic approach.

Therefore, in realistic TVFF scenarios, besides the idle licensed band, time-variant channel state information (CSI) on the cognitive links, as the important network information, needs to be estimated to ensure good sensing performance and helps SU_Rs acquire a better communication quality.

In [60], the authors implemented OFDM-based secondary cognitive link by using USRP N210 platforms.

It is crucial that such estimated CSI is surely responsible for the communication quality of cognitive link as well.

We perform sequential search over at most three real variables for the case of single-input multiple-output (SIMO) cognitive link, and four real variables for the case of multiple-input single-output (MISO) cognitive link, respectively.

It is shown that the computational complexity for solving the formulated problems does not increase significantly with the number of receive (transmit) antennas in the cognitive link.

Simulation results show that the multiple-antenna configurations yield improved system performance compared to the case of single-input single-output (SISO) cognitive link.
