Q21.
Which of the following is a parameter used for co-ordination between aircraft and ground radio in HaveQuick?

a.

Song of the day

b.

Number of the day

c.

Word of the day

d.

Date of the day

Discuss
Answer: (c).Word of the day Explanation:HaveQuick is initialized with the parameters word of the day, time of the day, and a net number. It is given as input to pseudo random number generator to control frequency. Word of the day is a transmission security variable.
Q22.
AN/ARC-220 uses software realized ____

a.

FPGA

b.

ASIC

c.

GPP

d.

DSP

Discuss
Answer: (d).DSP Explanation:AN/ARC-220 is a high frequency radio operating in the range 2 – 29.999 MHz. It uses software realized DSP and is software capable. It offers secure voice and data communication.
Q23.
VanuAnywave is an example for software defined radio.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:VanuAnywave is a software defined system that uses off the shelf hardware and proprietary software. It provides software implementation of base transceiver station, base station controller, and transcoder and rate adaption unit modules of the base station subsystem.
Q24.
The network does not have a ____ to pose questions about the radio.

a.

standard categorization

b.

standard classification

c.

standard language

d.

standard definition

Discuss
Answer: (c).standard language Explanation:The inability to gain knowledge by asking questions due to the lack of a standard language and the inability to understand radio structure due to the lack of computationally accessible description are the primary factors for the overall lack of awareness in a radio.
Q25.
The model of equalizer should contain ____ knowledge about equalizers.

a.

non-automatic

b.

codified

c.

automatic

d.

non-codified

Discuss
Answer: (b).codified Explanation:The model of equalizer should contain codified knowledge about equalizers. Equalizer is included as a part of the modem software. The radio may be made aware that an equalizer’s time domain taps reflect the channel impulse response.
Q26.
Which among the following is a function of radio model?

a.

DSP

b.

RF conversion

c.

Coding

d.

User interface

Discuss
Answer: (c).Coding Explanation:A radio model should contain representation of it functions and components. Transmission, reception, and coding are examples of functions of radio. Antenna, RF conversion, and DSP are examples of components of radio.
Q27.
The CR prototype introduces ____ frames into the model based ____ architecture.

a.

Radio Knowledge Representation Language, coding

b.

Radio Knowledge Reasoning Language, reasoning

c.

Radio Knowledge Reasoning Language, coding

d.

Radio Knowledge Representation Language, reasoning

Discuss
Answer: (d).Radio Knowledge Representation Language, reasoning Explanation:The CR prototype introducesRadio Knowledge Representation Language frames into the model based reasoning architecture. The CR prototype improves the original framework of cognitive radio. This is achieved by introducing machine learning, natural language processing, and radio architecture.
Q28.
Baseband processor hosts ____ software.

a.

encoding

b.

decryption

c.

protocol

d.

encryption

Discuss
Answer: (c).protocol Explanation:The internal structure radio model should aid system level interactions with the network. A detailed report on internal capabilities and the ability to download new capabilities when required must be made possible by the radio model. For example, the baseband processor contains protocol and control software.
Q29.
Which among the following is considered as second level capability in radio cognition?

a.

Pre-programmed

b.

Goal-driven

c.

Radio aware

d.

Context aware

Discuss
Answer: (d).Context aware Explanation:Context awareness is responsible for obtaining the context of external communication with minimal user involvement. Natural language, societal roles, and discourse are a part of model scope.
Q30.
A conventional programmed digital radio or a software radio is represented by level ____ capability.

a.

one

b.

two

c.

six

d.

zero

Discuss
Answer: (d).zero Explanation:The level zero capability represents a radio with no model based reasoning capability. It is called as pre-programmed radio model and does not have a model scope.
