Detailed performance evaluations of the fixed vs. the dynamic channel assignment schemes have been published by various authors. In this thesis, the performance of the hybrid channel assignment scheme, under various loading conditions is studied, by using simulation results of a cellular mobile communications system that has forty cells. A conclusion is reached as to when it is best to use hybrid or fixed channel assignment schemes.90 p.Engineering, Electronics and Electrical.Thesis
