1.	Which of the following can reduce the probability of non-recoverable fade depth?(a) Diversity(b) FEC(c) Interleaving(d) FEC and InterleavingThe question was posed to me in a job interview.My doubt is from Antenna Tradeoffs topic in section Technology Tradeoffs in Software Defined Radio of Cognitive Radio
Answer» The correct choice is (a) DIVERSITY To explain: Diversity TRANSMISSION and reception can reduce the probability of non-recoverable fade depth. It tends to choose the SIGNAL with MAXIMUM strength, improving the error floor. FEC and interleaving are useful for compensating the erasure CAUSED by fading.
