Architecture of a multi-cell centralized packet access system

We present an architecture for a system with multi-cell centralized packet access. In micro- or pico-cellular environments, the coverage overlap by adjacent antenna units arises naturally, which means that a signal emitted by a mobile terminal is multiple received. The whole service area of the system is parceled out into small coverage zones, to which channels are dynamically allocated. For such a dynamic channel allocation to be effective, the system has to attach the mobile terminals to the zones of allocation, based on the strength of the received signal. We study the problem of this fine-localization of the mobile terminals in the presence of fast fading
