Interference suppression by joint demodulation of cochannel signals

  • Chapter
GSM Evolution Towards 3rd Generation Systems

Abstract

Inter-cell cochannel interference (ICCI) is an inherent problem in all cellular systems due the necessity to reuse the same frequencies after a certain reuse distance. In GSM, the fact that the number of nearby cochannel interferers is relatively small leads to a high probability of a dominant interferer (DI). Hence, suppression of DI alone provides substantial capacity improvement for GSM. The paper summarises different aspects of interference suppression by joint demodulation of cochannel signals in the GSM system. The probability of DI is investigated by network simulations. Moreover, receiver algorithms are described and receiver performance analysis is provided. In addition, requirements that the application of the technique poses for the GSM systems are explained.
