Abstract

Multiband (or multi-carrier) CDMA is a promising approach to increasing the capacity of CDMA systems. The measurement based allocation (MBA) algorithm was previously proposed for allocating new calls to bands based on measured path gains. MBA introduces asymmetry between bands. This paper calculates the average other-cell interference in MBA systems and shows that the system capacity can be increased by loading different bands unequally. It also investigates the interaction of band allocations in neighbouring cells.
