Use of side information in frequency-hop packet radio network protocols
M.B. Pursley, H.B. Russell · 2002
Reliable data distribution within spread-spectrum packet radio networks requires high performance from the communication links and the network protocols. Side information can be extracted from the received signals, and this information can be used to improve the quality of the links and to aid the network protocols in establishing reliable routes in the network. Reliable side information is obtained in the slow-frequency-hop (SFH) receiver from the demodulation of test symbols that are inserted into the message stream at the transmitter. Results are reported on an evaluation of techniques and algorithms for using this side information to enhance link and network performance in SFH spread-spectrum packet radio networks.>
