Question

Environment based method has ____ waveform based method.

a.

higher complexity than

b.

lower complexity than

c.

equal complexity as

d.

equal time duration as

Posted under Cognitive Radio

Answer: (b).lower complexity than Explanation:Seamless positioning involves maintenance of position accuracy regardless of changes in channel environment. Waveform based approach and environment sensing based approach are the two techniques employed to achieve seamless positioning. Waveform based approach requires large database of all existing and future waveform and hence is more complex than environment sensing based method.
