1.	Which of the following is a drawback of zero forcing algorithm?(a) Long training sequence(b) Amplification of noise(c) Not suitable for static channels(d) Non zero ISII had been asked this question in final exam.Enquiry is from Algorithms for Adaptive Equalization in division Equalization, Diversity and Channel Coding of Wireless/Mobile
Answer» Correct choice is (b) Amplification of noise The best explanation: The ZERO FORCING algorithm has the DISADVANTAGE that the inverse filter may EXCESSIVELY amplify noise at FREQUENCIES where the folded channel spectrum has high attenuation.
