Question

Which of the following is not an algorithm for equalizer?

(a) Zero forcing algorithm

(b) Least mean square algorithm

(c) Recursive least square algorithm

(d) Mean square error algorithm

This question was addressed to me during an interview.

Origin of the question is Algorithms for Adaptive Equalization in chapter Equalization, Diversity and Channel Coding of Wireless/Mobile

Answer 1

Right option is (d) Mean square error algorithm

Explanation: Three classic equalizer algorithm are zero forcing (ZF) algorithm, least mean squares (LMS) algorithm and recursive least squares (RLS) algorithm. They offer fundamental insight into algorithm design and operation.
