Q11.
Which among the following describes the functions of cognitive radio?

a.

Define personalities

b.

Monitor knowledge

c.

Define antenna direction using pre-stored tables

d.

Support plug and play

Discuss
Answer: (b).Monitor knowledge Explanation:The cognition functions of a cognitive radio include monitoring and constructing knowledge, particularly of repeated actions and characteristics exhibited by user, surroundings, and radio. This helps information services to match the preferences of the user.
Q12.
What degree of capability is achieved by the installation of a GPS receiver in a radio?

a.

Aware

b.

Adaptive

c.

Cognitive

d.

Programmable

Discuss
Answer: (a).Aware Explanation:An aware device can obtain useful information. A device with GPS receiver is capable of sensing its location. However, a device becomes adaptive only when it uses the information for an application such as a map.
Q13.
How can a radio be trained to accept commands from one owner entity?

a.

Perception functions

b.

Sensory functions

c.

Awareness functions

d.

Adaptive functions

Discuss
Answer: (a).Perception functions Explanation:Perception functions can sense and trace known, unknown, and background information at all time. It is considered as a sub-category of cognition functions. The ability to accept commands from a particular entity and ignore all other entities is provided by perception functions.
Q14.
Which among the following categories include an accelerometer?

a.

Global effectors

b.

Environmental sensors

c.

Local effectors

d.

User interface sensors

Discuss
Answer: (b).Environmental sensors Explanation:Environmental sensors measure various characteristics in the surrounding domain. This includes temperature, vibration, power, exposure to light, position of sun, velocity, etc. It enables perception.
Q15.
Adaption may be pre-programmed.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Awareness enables adaption. Adaption is ability to direct a change according to input obtained from sensing. Adaption may be achieved without introducing learning through pre-programming. However, it is not possible to program all possible changes hence the next level of capability cognition is required.
Q16.
What method may introduce a trade-off between time and space in cognitive radio structure?

a.

Introduction of fully programmed solutions

b.

Introduction of partial solutions

c.

Introduction of real time solutions

d.

Introduction of large memory

Discuss
Answer: (b).Introduction of partial solutions Explanation:The introduction of partial solutions help in solving complex problems because a subset of problems relating to the complex problem will be solved first. The number of calculations may not be completely reduced but there is slight development in the overall computational burden.
Q17.
What is the full form of NP complexity?

a.

Non-deterministic polynomial time

b.

Non-linear polynomial time

c.

Non-probabilistic polynomial time

d.

Non-trainable polynomial time

Discuss
Answer: (a).Non-deterministic polynomial time Explanation:The non-deterministic polynomial time is a complexity class in the computational complexity theory. It is used to differentiate decision problems. NP is a collection of decision problems. When a decision results in action, it must have proof that can be confirmed in polynomial time by a deterministic Turing machine.
Q18.
Which among the following is a characteristic that need not be compulsorily present to overcome self-referential inconsistency in cognitive radio?

a.

Definition of process as a priori tightly bounded time epochs

b.

Step counting function

c.

Susceptible to Gödel-Turing condition

d.

Pre-defined actions that uses O (1) resources

Discuss
Answer: (c).Susceptible to Gödel-Turing condition Explanation:In order to computationally support real time transmission and reception, a process must be defined in priori tightly bounded time epochs. A pre-defined action that uses O (1) resources is defined in advance and a reliable step counting function must be present. This will help in avoiding unpredictable usage of resources and unpredictable self-referential loops.
Q19.
Which among the following is not a part of the cognition subsystem?

a.

Inference hierarchy

b.

Cognition cycle

c.

Organisation

d.

Channel state

Discuss
Answer: (d).Channel state Explanation:The information services exhibit cognitive behaviour by using a set of design rules, functions, and components defined by the cognitive radio architecture that allow continuous growth through easy updates. The section of the cognitive architecture responsible for cognitive behaviour consists of inference hierarchy, cognition cycle, and temporal organisation.
Q20.
How does the cognition cycle operate?

a.

Active

b.

Reactive

c.

Passive

d.

Activated

Discuss
Answer: (b).Reactive Explanation:he cognition cycle carries out its functions in a reactive sequence. Stimuli from the outside world are accepted by the sensors. The information is passed to the cognition cycle to generate a response.
