Abstract : This document lists and describes the usage of the variables in the Decision-Feedback Equalizer Simulation (DFES) program which was written for the Naval Ocean Systems Center by Signatron, Inc. The DFES program can transmit QPSK or BPSK through an hf channel. The channel can have fading, doppler and multipath. The transmission can be received and demodulated by a Desicion-Feedback Equalizer with one of four weight update algorithms: Kalman, LMS, fixed, and Rake. (Author)
