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 received signals that are embedded in noise and interference, 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. We have carried out the design, development, and evaluation of techniques and algorithms for developing side information and using it effectively to aid link and network performance in spread-spectrum packet radio networks. We have found that reliable side information can be obtained from the demodulator and decoder in the radio receiver, and that it can be used effectively on the links and in the network protocols to improve the overall performance of the radio network.
