Adaptive signal selection for dispersive channels and its practical implications in communications system design
Abstract
Possible techniques are considered whereby the operation of an HF communications system could be made adaptive in response to the state of the channel. Adaptive RF equipment, source encoding/decoding and channel encoding/decoding procedures are described and their interactions discussed. Adaptive signal selection implies adaptive signal generation and processing equipment. Possible formats for such units are outlined, together with the inputs required for their operation and the advantages accruing from their use.
