Which among the following would result in increased out-of-band reject

1.	Which among the following would result in increased out-of-band rejection at receivers while broadcasting?(a) Periodic transmissions(b) Increased transmission power(c) Frequency reuse(d) Close band spacing between stationsI have been asked this question in an interview for internship.This key question is from Next Generation Wireless Network topic in division Next Generation Wireless Network of Cognitive Radio
Answer» Right option is (d) Close band SPACING between stations Explanation: The close band spacing between stations is a potential method for increasing the station density. HOWEVER it CAUSES increased out-of-band rejection at the receivers. Reduction of TRANSMISSION and increased FREQUENCY reuse are other approaches for increasing station density. However these methods result in reduced coverage.
