Q271.
Which among the following learning methods does not involve explicit planning?

a.

Channel based

b.

Network based

c.

Reactive

d.

Adaptive

Discuss
Answer: (c).Reactive Explanation:Reactive reasoning and learning does not involve explicit planning. The cognitive system can be programmed to respond to user voice commands and common device configurations. The adaptive cognitive radio stores user preferences, incorporates speech recognition models, and user intent models to learn from past experiences.
Q272.
Which among the following is a disadvantage of network based reasoning?

a.

False recognition

b.

Protocol standardization

c.

High memory requirements

d.

Exhaustive resource utilization

Discuss
Answer: (b).Protocol standardization Explanation:Cognitive radio can utilize a large network of services to complete user requests. Network based reasoning can collect information localized to a location such as finding restaurants, detecting traffic, detecting weather, etc. It introduces flexibility in the radio and reduces the amount of resources used. However, it exhibits poor latency and requires protocol standardization.
Q273.
Mixed excitation linear prediction coding standard is employed for speaker stress characterization.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:Mixed excitation linear prediction coding standard was developed for speech compression. It supports bit rates of 600 bits/s, 1200 bits/s, and 2400 bits/s. It can be employed for background noise suppression by integrating with spectral subtraction.
Q274.
What is a radio environment map?

a.

Radio environment map represents a collection of access points in the immediate vicinity

b.

Radio environment map provides insight on radio environment over multiple domains such as regulation and frequency emission

c.

Radio environment map represents cognitive radios in the immediate vicinity

d.

Radio environment map represents cognitive radios participating in cooperative sensing

Discuss
Answer: (b).Radio environment map provides insight on radio environment over multiple domains such as regulation and frequency emission Explanation:Radio environment map provides an abstraction of real time radio environment. It defines the radio environment of cognitive radio using multiple characteristic features such as geographical conditions, regulation, policy, capability of radio equipment, and radiofrequency emissions.
Q275.
Which among the following statements is false about the radio environment map?

a.

Radio environment map does not require complex circuitry in the user device

b.

Radio environment map records radio frequency emissions

c.

Radio environment map is a spatiotemporal database

d.

Available resource map is extended from a radio environment map

Discuss
Answer: (d).Available resource map is extended from a radio environment map Explanation:Radio environment map is a spatiotemporal database capable of supporting cognitive functionalities such as planning, learning, and reasoning of the user equipment. The radio environment map is an extension of the available resource map which includes all radio activities in the unlicensed wide area network in real time.
Q276.
Which among the following incorporates knowledge to support cognition functionality?

a.

External administration support

b.

Internal administration support

c.

External network support

d.

Internal network support

Discuss
Answer: (c).External network support Explanation:External networks are other networks in an area with knowledge to promote cognition functionality. For example, a sensor network created to gather information on cognitive radio networks. Internal network offer communication services and cognition functionality.
Q277.
Which among the following is an advantage of spectrum sensing with radio environment map?

a.

High sensitivity

b.

Low transmission power

c.

Reduction in observation time

d.

High dynamic range

Discuss
Answer: (c).Reduction in observation time Explanation:The radio environment map holds both present and past radio environment information. Spectrum sensing with prior knowledge is more effective than continuous scanning of the entire radio spectrum. Consequently, the observation time, cost, and energy consumption of radio can be reduced.
Q278.
Which among the following is achieved by combing learning with data mining in the radio environment map?

a.

Observation intelligence

b.

Learning

c.

Network intelligence

d.

Resource intelligence

Discuss
Answer: (c).Network intelligence Explanation:The incorporation of information obtained from reasoning, learning, and data mining in the radio environment map provides network intelligence. Network nodes obtain cognitive capabilities through network intelligence irrespective of the cognition capability of subscriber radios. Cognition capability can be provided to the legacy networks by combining them with the radio environment map.
Q279.
Which among the following units communicates with radio environment map in legacy radios?

a.

Local control and access manager

b.

Local bus manager

c.

Specialized processor

d.

Network radio resource manager

Discuss
Answer: (d).Network radio resource manager Explanation:The radio environment map aids legacy radios or hardware reconfigurable radios by providing smart network operation by introducing cognitive strategies to the network radio resource manager. While in cognitive radios, it aids in situational awareness and adaptations.
Q280.
Which among the following statements is false about a radio operating with the radio environment map?

a.

Aware of application layer operations

b.

Aware of physical layer operations

c.

Awareness of performance metrics

d.

Incompatibility with underlying radio access technology

Discuss
Answer: (d).Incompatibility with underlying radio access technology Explanation:Radio environment map enables a radio to be aware of performance metrics such as data rate, spectral efficiency, etc. A radio with a radio environment map is comprehensive of each layer of protocol stack under different and varying radio environments. Radio environment map is compatible with underlying radio access technology regardless of the cognition capability of user radio.
