Skywave communication techniques. Decision feedback equilization for serially modulated spread-spectrum signals in the HF band yields improved reliability
Abstract
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.
