1.	Which of the following is not a non-linear equalization technique?(a) Decision feedback equalization(b) Maximum likelihood symbol detection(c) Minimum square error detection(d) Maximum likelihood sequence detectionThe question was asked in a national level competition.The doubt is from Equalization Techniques topic in section Equalization, Diversity and Channel Coding of Wireless/Mobile
Answer» The CORRECT answer is (c) Minimum SQUARE error detection Best explanation: Decision feedback equalization, maximum likelihood SYMBOL detection and maximum likelihood sequence detection OFFERS non-linear equalization. They offer improvements over linear equalization TECHNIQUES and are used in most 2G and 3G systems.
