Abstract

"This paper presents a performance analysis of two QPSK detection schemes for flat Rayleigh fading channels. Closed-form expressions for the bit error probability of both schemes are obtained. It is shown that they present the same error probability and a complexity analysis is carried out to determine the best scheme in terms of the number of operations (multiplications, divisions, subtractions and comparisons) executed by each detector."
