1.	Which of the following do not impact bit error rate in mobile communication systems?(a) Mobile velocity(b) Channel delay spread(c) Modulation format(d) Base stationI have been asked this question in a job interview.Enquiry is from Modulation Performance in Fading and Multipath Channels topic in chapter Modulation Techniques for Mobile Radio of Wireless/Mobile
Answer» The correct option is (d) Base station Best explanation: The mobile velocity, channel DELAY SPREAD, interference levels and modulation formats all independently impact the raw bit error rate in mobile COMMUNICATION systems. And simulation is a POWERFUL way to design or predict the PERFORMANCE of wireless communication links.
