1.	Why is cooperation required in spectrum sensing?(a) Elimination of base-station(b) Elimination of xG users(c) Interference avoidance(d) Improvement of sensing accuracyI got this question by my school principal while I was bunking the class.The query is from Next Generation Wireless Network topic in section Next Generation Wireless Network of Cognitive Radio
Answer» Correct OPTION is (d) Improvement of sensing accuracy To explain: The cognitive RADIO user monitors and studies the local radio environment to identify the current spectrum availability. The information gathered by each user is SHARED between its NEIGHBOURS. This practice is known as cooperation in sensing and it improves the sensing accuracy.
