A Practical Culling Strategy to Assist Frequency Assignment for Land Mobile Radio Systems

Abstract

This pape r d e s c r i b e s a p r a c t i c a l c u l l i n g s t r a t e g y to a s s i s t f r e q u e n c y a s s i g n m e n t s for Land M o b i l e ra d i o s y s t e m s in the t w o s i g n a l third-order receiver i n t e r m o d u 1 at i o n i n t e r f e r ­ ence analysis. This strategy is used to identify the potential conflict s i t u a t i o n s w h i c h have a r e l a t i v e l y hig he r p r o b a b i l i t y of interference so that the number of calculations that have to be performed in an interference analysis may be m i n i m i z e d . The r e s u l t s of the a n a l y s i s are presented on a graph depicting the relationship between the two culling limits of distance and fre qu enc y separation.
