Abstract :
(For Pt.I see ibid., vol.31, no.3, p.280-92, Aug., 1989). A mathematical model using linear algebra has been developed to generate interference-free simplex channel assignment grids for base stations in the VHF land mobile band for large urban areas. The frequency assignment model checks for interference from adjacent channels, desensitization, transmitter intermodulation, and receiver intermodulations. High-density grids are presented for single- and multiple-frequency (sharing) assignments for a single square region of side 32 km. The application of the model to a square region of side 96 km is also described
