Investigations using the theoretically calculated Fundamental Wave spectrum (periods) of those objects, its Megaspectroscopy (including helioseismology and asteroseismology for the Sun and stars) lead to the reconstruction of the dynamical and physical properties, and their internal and external structure.

An intense stationary sinusoid from the spectrum with period T∼6500 yr, the 4th harmonic of the period of equinox precession, correlates with the time variations of the geomagnetic dipole moment.

If we consider the set of channel states in the previous spectrum access period as the system state, denoted by at spectrum access period, then the previous assumption implies a completely observable system state, which substantially simplifies the analysis.

We assume that each secondary user is able to sense only one channel during the spectrum sensing period and transmit over only one channel during the data transmission period.  .

The equation used to determine the FVO for a 10.2 bp periodicity is given below

Here, L is the total number of observation samples made by a CR-based HAN device within the local spectrum sensing period T s such that L=T s /τ, where τ is the sampling period.

Note that this does not contradict the assumption that a secondary user can sense only one channel during the spectrum sensing period since the secondary user can continue to sense other channels during the data transmission period (suppose that the signal from primary users can be well distinguished from that from secondary users, e.g., using different cyclostationary features [22]).

Some studies referred in this paper define a routing metric that considers the PUs' spectrum occupancy period.

In Sections 3 and 4, we consider the case in which all secondary users have full knowledge of channel states in the previous spectrum access period (complete observation).
