Abstract
This paper gives performance results for transversal-filter equalization of Quadri phase phase-shift-keyed (QPSK) signals with two-component multipath and demodulator phase error. An analytical expression for optimum, minimum mean-square-error tap weights in terms of the multipath and signal parameters is given. Probability of error results for no equalization and equalization with adaptive decision-feedback tap-weight adjustment are compared. The results show that significant improvement can be obtained with relatively simple equalizer structures. Copyright © 1974 by The Institute of Electrical and Electronics Engineers, Inc.
