1.	Which among the following is the impact of primary user interference in the physical layer?(a) High bit error rate(b) High delay(c) High collision(d) High energy demandI have been asked this question in examination.I would like to ask this question from Next Generation Wireless Network topic in section Next Generation Wireless Network of Cognitive Radio
Answer» The correct ANSWER is (a) High bit ERROR rate Explanation: The effect of primary user interference in the physical layer is a high bit error rate. It can be mitigated by ADJUSTING the CODING DYNAMICALLY. It also can be resolved by allowing higher layers to tackle interference for a period of time.
