Skywave Communication Techniques. Decision Feedback Equalization for Serially Modulated Spread-Spectrum Signals in the hf Band Yields Improved Reliability

摘要

Summarizes the Skywave Communication task. Presents some results of the work on wide-band channel modeling, adaptive equalization, and the field test, which demonstrated that serial modulation spread-spectrum signals can be used to provide reliable communication at hf under multipath conditions.
