Comparison Of Neural Network Applications For Channel Assignment In Cellular Tdma Networks And Dynamically Sectored Pcs Networks, William S. Hortos

Electrical Engineering and Computer Science Faculty Publications

The use of artificial neural networks (NNs) to address the channel assignment problem (CAP) for cellular time-division multiple access and code-division multiple access networks has previously been investigated by this author and many others. The investigations to date have been based on a hexagonal cell structure established by omnidirectional antennas at the base stations. No account was taken of the use of spatial isolation enabled by directional antennas to reduce interference between mobiles. Any reduction in interference translates into increased capacity and consequently alters the performance of the NNs. Previous studies have sought to improve the performance of Hopfield- Tank …
