Q121.
Choose the appropriate labels to complete the diagram.

a.

Control, training, model update

b.

Training, control, model update

c.

Model update, control, training

d.

Model update, training, control

Discuss
Answer: (a).Control, training, model update Explanation:The diagram depicts the steps involved in the application and improvement of radio skills. The radio skills developed from static and active knowledge available in observe phase is used to control radio personalities. The radio skill model is also continually updated by using information from act phase.
Q122.
Which among the following phases do the components B1, B2 belong?

a.

Act

b.

Decide

c.

Plan

d.

Orient

Discuss
Answer: (d).Orient Explanation:The component B1 and B2 belong to the orient phase of cognition cycle. B1 evaluates word and phrase bindings to form dialog states. B2 is responsible for creating action requests based on binding and dialog state.
Q123.
Which among the following phases do the components A1, A2, A3 belong?

a.

Observe

b.

Orient

c.

Act

d.

Decide

Discuss
Answer: (a).Observe Explanation:The components A1, A2, and A3 belong to observe phase of the cognition cycle. A1 is called as input map which connect the world unit to sensory data. A2 is a transformation component that converts atomic stimuli into primitive sequence. A3 is projection component that binds sequence to bindings.
Q124.
Which among the following correspond to the point plotted in the graph?

a.

COTS Handset

b.

Programmable radio

c.

Software defined radio

d.

Virtual radio

Discuss
Answer: (c).Software defined radio Explanation:The graph depicts the design space of software defined radio. The plotted point corresponds to an ideal software defined radio. An ideal software radio is one in which every physical layer function is software defined. The radio must be flexible, multifunction, programmable, and easy to upgrade.
Q125.
Which among the following correspond to the point plotted in the graph?

a.

COTS Handset

b.

Digital cell site

c.

Software defined radio

d.

Cognitive radio

Discuss
Answer: (b).Digital cell site Explanation:The graph depicts the design space of software defined radio. The plotted point corresponds to the digital cell sites. These devices are typically constructed using Application Specific Integrated Circuits (ASICs). The devices depend greatly on digital filter ASICs for frequency translation and filtering. They access the spectrum at IF frequency.
Q126.
Which among the following gives the full form of RXML?

a.

RicXon Macro Language

b.

RicXon Micro Language

c.

RoXen Macro Language

d.

RoXen Micro Language

Discuss
Answer: (c).RoXen Macro Language Explanation:RoXen Macro Language is a server scripting language with syntax similar to that of HTML. The functions which impart external communication and internal reasoning in a self-aware radio are implemented using RXML.
Q127.
Which among the following statements is true about the RXML statements given?

<Cognitive radio platform/>

<Functional-Components>

<Func1/><Func2/><Func3/><Func4/><Func5/><Func6/>

</Functional-Components>

</Self>

a.

The hardware and software platform is dependent of the functional components of the cognitive radio

b.

The functional components of the cognitive radio are dependent on the hardware and software platform

c.

The hardware and software platform are independent of each other

d.

The hardware and software platform is independent of the functional components of the cognitive radio

Discuss
Answer: (d).The hardware and software platform is independent of the functional components of the cognitive radio Explanation:The organisation of the statements defines a cognitive radio with six functional components. The enclosure of the functional components within <Functional-Components> and </Functional-Components> indicate that the hardware and software platform is independent of the functional components of the cognitive radio.
Q128.
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.
Q129.
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.
Q130.
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.
