A method af assigning transmitting power and frequency to narrow band links exposed to nonselective fading and self induced interference in an HF radio data network is suggested. The method uses vector optimization by means of a feedforward neural network.The network performance measure used is a weighted sum of mutual information for all links in the network. The suggested assignment method can be used for power and frequency planning using simulated fading and interference data. It can also be used with actual measured link data in an adaptive on-line system. The method is capable of handling links utilizing frequency diversity and can also take LPD/LPI aspects into account. Simulation results indicate that the degree of correlation in space and frequency between different links palys ab important role in the assignment process.
