In other words, SpaceX was directly controlling the vehicle based on new sensor readings, adding a new level of accuracy in sensing the distance between Grasshopper and the ground, enabling a more precise landing".
In sum, fluctuations of nutrient concentrations, limits to detection of concentration differences, and gene expression noise will conspire to prevent high-accuracy sensing of nutrient concentrations needed for optimal growth.
Since the accuracy of the spectrum map depends on the accuracy of spectrum sensing techniques, the RRM server should acquire the assistance from a certain number of WSAPs that provide their spectrum sensing results of a higher accuracy of spectrum sensing techniques.
However, the loss function in each proposal is often formulated based on the intended application (e.g. throughput, sensing accuracy, or hand-off success rate).
As the given values for sensing accuracy, any p d satisfying the condition p d ≥ 1 − I ¯ is used while p f is fixed to 0.1.
In other words, the update of the occupancy status of every channel occurs asynchronously with the spectrum sensing results retrieved from the diverse accuracy of spectrum sensing techniques, and that is the reason why the RRM server maintains per channel.
Nowadays, the silicon piezoresistive pressure sensor is a mature technology in the industry, but its requirement in terms of sensing accuracy and stability is more rigorous than that of many advanced applications.
Therefore, in order to increase the accuracy of sensing results and further improve the network performances, the cooperative spectrum sensing and distributed DSA protocols should be jointly designed based on the cross-layer approach.
There is a trade-off between estimation accuracy and sensing overhead.
In [54], Chen et al. proposed a CSS-RA, which utilizes the spatial diversity to improve the accuracy of sensing outcomes.
