Question

Discretization of multipath delay axis of impulse response into equal time delay segments is called __________

(a) Excess delay bins

(b) Delay bins

(c) Discrete bins

(d) Digital bins

The question was posed to me in class test.

Query is from Impulse Response Model of a Multipath Channel in section Mobile Radio Propagation: Small – Scale Fading and Multipath of Wireless/Mobile

Answer 1

Correct option is (a) Excess delay bins

Easiest explanation: It is useful to discretize the multipath delay axis of the impulse response into equal time delay segments called excess delay bins. The technique of quantizing the delay bins determines the time delay resolution of the channel model.
