1.	The over-determined set of equations can be solved using(a) Zero forcing(b) Minimum mean square error(c) Zero forcing & Minimum mean square error(d) None of the mentionedThis question was addressed to me during an interview for a job.Origin of the question is Equalization and Non Coherent Detection topic in section Baseband Demodulation and Detection of Digital Communications
Answer» RIGHT OPTION is (c) Zero forcing & Minimum mean square error For explanation: The matrix x in transversal equalizer if non square with dimensions 4N+1 and 2N+1. Such equations are called as over-determined set. This can be SOLVED by two methods called as zero forcing method and minimum mean square error method.
