When modularity theory was introduced in cognitive science (Fodor 1983), central cognition cognition in the narrow sense was characterized as non-modular, and as sharply distinct from modular peripheral systems, such as those governing perception and motor control (plus, as Fodor says, language).
Then, a CR positioning system has been introduced in [71] to facilitate cognitive location sensing.
In order to improve the spectrum utilization, CR has been introduced in the underwater communication network, called as cognitive sonar communication networks (CSCN) [6].
The regulatory concept presented under the name cognitive radio has been introduced in [1] to make spatially and temporarily unused fragmented frequency bands usable and thus to improve the spectral efficiency.
Two terms have been introduced in describing this behavior: 'cognitive neglect', which suggests that patients perceive their involved limb as feeling foreign to them, and 'motor neglect', which describes situations in which the patients need to focus mental and visual attention to move their limb [ 107].
In [23], a new cooperative scheme is introduced in a cognitive network with several relay nodes.
New economic terms such as 'risk aversion', 'risk-rewarded trade-off', and 'economic welfare' are introduced in relation to cognitive radio framework.
Cognitive cooperation is introduced in the second phase, where each base station transmits on two frequency bands to the scheduled users in both base stations, by means of an appropriately chosen distributed space time code based on the Golden code.
The remainder of this paper is organized as follows: the system model of cognitive radio is introduced in Section 2; the channel capacities of memoryless and finite state channels are discussed in Sections 3 and 4, respectively; the numerical results are provided in Section 5; finally, the conclusions are drawn in Section 6.
Since this study considers only the simple evaluation of users and does not spare any thought for cognitive psychology (for example, Gestalt psychology), cognitive psychology could not be introduced in this study.
