Question

Which of the following statements is false?

(a) The intra cellular handoffs are less in adaptive array compared to switching beams

(b) Noise interference cannot be detected in adaptive arrays effectively compared to switching beams

(c) Advanced digital signal processors are used in adaptive arrays

(d) Algorithms used in adaptive array is more complex than switching beams

This question was posed to me in my homework.

Question is from Adaptive Array topic in portion Phased, Adaptive and Binomial Arrays of Antennas

Answer 1

Right answer is (b) Noise interference cannot be detected in adaptive arrays effectively compared to switching beams

The best I can explain: Adaptive array is used to guide the beam in desired direction and place nulls in unwanted direction/interference. More complex algorithms are used in adaptive arrays and also advance digital signal processors are used to different the desired user and the unwanted signals/users.
