Question

Which among the following is not a common feature between the time of arrival and time difference of arrival?

(a) Straight-line of sight

(b) High resolution system clock

(c) Propagation at speed of light

(d) Shape of curve

I had been asked this question in unit test.

I'd like to ask this question from Next Generation Wireless Network topic in portion Next Generation Wireless Network of Cognitive Radio

Answer 1

Correct option is (d) Shape of curve

To explain: Time of arrival and time difference of arrival are two time-based approaches. Both approaches require a high-resolution system clock with signals that propagate at the speed of light. It requires a straight line of sight path as the signal delay directly relates to the line of sight distance.
