Signal-to-interference calculations for balanced channel assignment patterns in cellular communications systems
S.-W. Wang, Stephen S. Rappaport · IEEE Transactions on Communications · 1989
The effects of adjacent channel interference, together with cochannel interference, for fixed channel assignment patterns in cellular communications systems are considered. Thorough consideration is given to interference produced by emissions in neighboring channels, including immediately adjacent as well as nonimmediately adjacent channels. An approximate mathematical analysis is presented that permits a more complete calculation of the median mobile-to-base and base-to-mobile signal-to-interference ratios than has been available. Patterns of cell frequency assignment that have regularity properties with respect to the performance measures are determined. Formulas for comparison of signal-to-interference-ratio performance for alternative cell/frequency assignment are derived.>
