| Abstract: | In this paper, the impact of co-channel and adjacent channel interference in mobile cellular radio systems on the cellular system capacity are studied. Simple empirical expressions for average signal to co-channel, signal to adjacent channel and signal to total interference ratios are obtained. The simple empirical results developed in this paper are easier to use in a cellular system design. The maximum number of bits/sec that can be transmitted over a cell area for a given bit error rate and total bandwidth, is proposed as a new definition of capacity of digital cellular systems. The capacity of a cellular system is shown to depend on the excess bandwidth and the number of active users. |
