Question

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 detection

The 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 1

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.
