摘要

Adaptive decision feedback equalization is one of several mitigation techniques that can be employed to improve the performance of narrowband HF modems operating under time and frequency selective channel conditions. The decision feedback equalizer (DEF) is described and several adaptation algorithms are derived. Computer simulations of BPSK HF modems were used to compare link performance (in terms of bit error rate) with and without employment of an adaptive DFE. Also the performance was quantified versus channel disturbance parameters for a specific 2400 baud modem.
