Bandwidth Considerations in a JANET System

Some of the considerations which influence the choice of transmission bandwidth in a JANET system are discussed in this paper. It is shown that the mean rate of transfer of information increases with bandwidth, for bandwidths in the range currently contemplated, in spite of the consequent decrease in the duty cycle. A system designed to maintain a constant snr by varying the bandwidth with received signal power is discussed, and its advantage over a fixed bandwidth system is calculated.
