Co-channel and Adjacent Channel Interference Calculations in Cellular Communications Systems

Blog Article

Signal to Interference ratio (S/I) calculations for corner excited cellular communications systems based on median mobile-to-base and base-to-mobile signal powers for co-channel interference and immediately adjacent as well as non- immediately adjacent sweet life carts channel interference is presented.The mathematical model includes most related system parameters, such as, cluster size, filter characteristics, propagation exponent, tier coverage, and directional antennae front-to-back ratio.Both mobile-to-base and base-to-mobile cellular communications are investigated.

The calculated results proved that the effect of adjacent channel interference compared to co-channel interference cannot be ignored in general and may have severe performance voyage et cie discount code degradation under some specific operating environments, for a particular system architecture.
