1.	What is the advantage of using matched filter detection?(a) Rapid increase in processing gain(b) Simultaneous detection(c) High accuracy(d) Low power consumptionI had been asked this question during an interview.The query is from Next Generation Wireless Network in division Next Generation Wireless Network of Cognitive Radio
Answer» Right CHOICE is (a) Rapid increase in processing gain For explanation: Matched filter DETECTION ACHIEVES HIGH processing gain rapidly due to coherency. However when accurate information is not available about the signal transmitted by the primary user, then the matched filter detection method exhibits poor PERFORMANCE.
